# amCharts 4 Changelog The format is based on [Keep a Changelog](http://keepachangelog.com/en/1.0.0/). Please note, that this project, while following numbering syntax, it DOES NOT adhere to [Semantic Versioning](http://semver.org/spec/v2.0.0.html) rules. ## [4.0.21] - 2011-01-11 ### Fixed - Issues that caused errors in Map an Percent charts on data update and dispose fixed. ## [4.0.20] - 2011-01-11 ### Fixed - Chart with `ColumnSeries` was failing with an error when `data` was updated. ## [4.0.19] - 2019-01-11 ### Fixed - `MapLineSeries` with direct `data` set were somewhat broken since last update. ## [4.0.18] - 2019-01-10 ### Added - JSON: Better id checking and error reporting. ### Fixed - Export menu no longer shows DATA menu for `MapChart` (and other charts if data is empty). - JSON: Some empty properties like `dummyData` were not being set properly. - Disposing a chart or series when `Legend` was enbled was resulting in error. ## [4.0.17] - 2019-01-09 ### Fixed - Dramatically improved performance for data-heavy charts (with 10s and 100s of thousands of data points). - `SmallMap` viewport indicator rectangle was positioned incorrectly. - Clicking on `SmallMap` was not moving map to corthis.component.rect location. - Lines from GeoJSON were not drawn by `MapLineSeries`. - Issue with multiple data points on the same date fixed (not all data points were visible at the end of selection). ## [4.0.16] - 2019-01-05 ### Added - New locales: Norwegian Bokmål (np_NO), Danish (da_DK). ### Changed - Renamed Swedish locale to `sv_SE`. ### Fixed - Interactions on MacOS Safari was broken sincle last update. ## [4.0.15] - 2019-01-04 ### Added - `color` property added to `LegendDataItem`. Can be used for coloring `label` or `valueLabel` text like `text = "[{color}] {name}"`. - `minZoomCount` added to `Component`. - Export now allows formatting numberic values as durations. Use newly added `durationFields` and `durationFormat` settings. ### Changed - Export: When exporting date to XLSX, date fields will now export as true date fields in Excel (which in turn will format them according to regional settings), unless `useLocal` is set to `false`. ### Fixed - Charts were not working properly in FireFox Extended Support Release. - Some computer setups were not properly registering mouse movement. - `legendSettings` was being ignored initially if legend was in external container. - "Week year" (format code `"YYYY"`) was not being properly calculated. ## [4.0.14] - 2019-01-02 ### Added - New setting `zoomStep` added to `MapChart`. Allows controlling zoom in/out speed. ### Fixed - `Series.hidden` did not work as expected. - World map did not work in Ember. - Eliminated multiple warnings in recent version of Chrome regarding wheel events being active. - Fixed mousewheel zoom in IEs. - Draggable/resizable items were not working properly on some Android browsers. - Setting `height` to a relative value for a horizontal `ColumnSeries` column template was not working propertly. ## [4.0.13] - 2018-12-26 ### Fixed - Charts were broken in IE9. ## [4.0.12] - 2018-12-24 ### Fixed - Cursor/mouse operations were somewhat broken in IE11 and lower. ## [4.0.11] - 2018-12-24 ### Added - `"disabled"` and `"enabled"` events added to `Sprite`. - `cursorTooltipEnabled` added to `XYSeries` If set to `false` cursor will not trigger bullet/item tooltips on series. ### Changed - IMPORTANT (CODE-BREAKING CHANGES) For performance reasons we no longer create axis elements if they are disabled. For the same reasons we disabled by `axis.ticks` and `axis.axisFills` by default. Previously to enable them you had to set their `strokeOpacity` and/or `fillOpacity` to non-zero. This no longer will work. You will need to set `disabled` to `false` instead. - `axisRanges` now take their default values from `dateAxis.axisRanges.template` items (`axisFill`, `grid`, `tick`, `label`). Previously they were using the defaults from `dateAxis.renderer.label` etc. This was not comfortable and counter-intuitive. ### Fixed - `XYChartScrollbar`'s value axis was calculating `min`/`max` with a very big step. - Ember plugin was throwing console errors. - Fixed occasional zoom-in issue on Mobile Safari. - `MapChart` mouse wheel zoom direction was inverted on some browsers. - Cursor was not snapping correctly to `DateAxis` items. - Multiple floating columns on the same category were disappearing when scrolling the chart. - Date range fills were off when zooming on Gantt Chart. - Overlapping tooltips problem solved. - When `snapToSeries` was set for a tooltip, it was flickering a lot on slower browsers. - `alignLabels = false` on a `PieSeries3D` was causing labels to be positioned incorrectly. - `PieSeries.dataFields.radiusValue` was not accounting for `chart.innerRadius`. - Dynamically updating `alignLabels` for `PieSeries` did not work correctly. - Legend: `itemValueText` only worked if `valueText` was set. - `ValueAxis` setting `maxZoomFactor = 1` was not working as expected. - Changing values for all data items sometimes was resulting in `ValueAxis` scale going into negative. - Some more tooltip and cursor related issues fixed. - Axis Fill did not properly fill the whole span when axis was scaled. ## [4.0.10] - 2018-12-20 ### Fixed - In some situations, when `geodataSource` had events set, it was producing error. - `DateAxis` was not rounding intervals properly, could display grid at `15:01`, `15:31` etc. - Cloning an object was cloning sometimes was causing event handlers to be duplicated. - A leftover console debug line was removed. ## [4.0.9] - 2018-12-19 ### Added - `snapToSeries` added to `XYCursor`. Allows setting series to which cursor lines should be snapped. Works if one of the axis of the series is `DateAxis` or `CategoryAxis`. Won't work if both axes are `ValueAxis`. - New example: Pie charts in Columns using JSON config. - Export: `emptyAs` added to both CSV and Excel export options. If set, missing values will be replaced with this value (default is empty string). - New event `"beforedisposed"` added to `Sprite`. Kicks in right before the element starts to dismantle itself. - Italian translation. ### Changed - Export: if no `dataFields` specify it will now look for fields in all of the data, not just the first line. - When creating a new state on an object, it will not automatically propagate itself on object's clones if `applyOnClones = true`. - Setting `Container`'s `setStateOnChildren` will now propage to the new value to its existing clones if `applyOnClones = true`. - In case `deepInvalidate()` is called on `Container`, it forces labels to redraw. - `filters` on `SpriteState` is now `List` (was `ListTemplate`). It's better for performance which does not require creating Filter template object. ### Fixed - Clicking a hoverable/clickable object was resultin in "over" and "out" events generated next to "hit". - JSON: properties to existing `List` items were not being applied properly. - Using geodata in Ember app was causing errors (Issue 672). - Export to CSV/Excel was following first line of data values. It now respects `dataFields` setting, and will replace missing values with `emptyAs` (new options setting). - Wheel-scrolling in MacOS Safari was very slow. - HTML-based tooltips were too small to fit the actual contents on MaCOS Safari. - `DateFormatter` was not parsing `"i"` format as local timezone, rather than UTC. - Sometimes bullets with `Rectangle` element in them were not positioned properly. - If category was named `"undefined"`, it was messing up label positions on `CategoryAxis`. - State's property value was not being applied if current value of the property was `undefined`. - Performance of `PieChart` and `RadarChart` improved dramatically under IEs. - In some cases `"ready"` event was not being fired. - `FunnelSeries` with 0 (zero) value slices was not rendered correctly. ## [4.0.8] - 2018-12-11 ### Added - `currentStep` added to `ColorSet`. Allows setting current position of the color iterator. - Adapters added for `Sprite` properties: `inertiaOptions`, `hitOptions`, `hoverOptions`, `swipeOptions`, `keyboardOptions`, `cursorOptions`. ### Changed - `nonScaling` of `AxisLabel` is no longer set to `true` by default, to improve performance. ### Fixed - `ValueAxis` was not updating its scale if series was hidden and animated theme was not enabled. - Zooming an `XYChart` with all values equal was broken. - Series in an `XYChartScrollbar` sometimes was not visible initially. - `ColumnSeries` was drawing 1px line for `null` value data items. - `DateAxis`' `snapTooltip = true` was working incorrectly with `skipEmptyPeriods = true`. - Logarithmic `ValueAxis` with axis breaks was resulting in stack overflows. - JSON: Chaining multiple adapters in an array (e.g. `adapter: [{...}, {...}]`), was not working. - JSON: Adding elements to `children` via array syntax was not working properly. - JSON: `Container` elements can now be created via JSON config. - Setting `dataFields` in `Export` was only affecting column names. Values for all data fields were still being included in export. ## [4.0.7] - 2018-12-07 ### Added - `snapTooltip` with default value `true` added to `DateAxis`. Cursor will snap to the nearest date at which series has values. ### Changed - Default value of `showOnInit` set to `false` for `TreeMapSeries`. ### Fixed - Solved tooltip overlapping bug. - In `TreeMap`, when series is toggled off, remaining series will be resized to take up freed space. ## [4.0.6] - 2018-12-06 ### Added - `snapTooltip` added to `XYSeries`, with default value `false`. If set to `true`, the series will show nearest available tooltip when cursor is over plot area. - Slovenian translation. ### Fixed - Automatic `DateAxis` interval detection improved. ## [4.0.5] - 2018-12-06 ### Changed - `DateFormatter` will now automatically format "negative" year values to "BC" (era) format. So not `"-1000"`, but `"1000BC"`. These are translatable via language. - `DropShadowFilter` of the tooltip removed. Instead it is now applied on background of tooltip. This helps to avoid text distortion. ### Fixed - Heat rules were not working if all the values were the same. Now middle value between min and max is applied in this case. - Updated algorithm to deal with date axes breaks. It's faster now and does not cause stackoverflow if the gaps are very big. - Series on `HeatMap` charts were ignoring scrollbars. - `DateAxis` was not properly placing labels if `location > 0` and grid interval was bigger than one time unit. - `DateAxis` with very big date difference (thousands of years) displayed too many grid/labels/ticks. - Masking of a sprite with a container updated. It now pays proper attention to container's position. - Automatic `DateAxis` interval detection improved. Previously it detected intervals like minutes, hours, days, years. Now it will detect intervals like 15 min, 30 min, 5 days etc. This can still be set manually using axis' `baseInterval` property. ## [4.0.4] - 2018-12-03 ### Added - `zoomLevel` and `zoomGeoPoint` properties added to `MapSeriesDataItem` and `IMapSeriesDataFields`. If set, these settings instead of automatically-calculated will be used when `zoomToMapObject()` method is invoked. ### Changed - `verticalCenter` and `horizontalCenter` is no longer applied to rotated axis labels. If you are setting `rotation` on axis labels, make sure to adjust these settings as well as per your requirement. ### Fixed - Setting `axis.renderer.inside` was ignored if set after chart was already initialized. - Changing `align` of the a sprite was ignored if set after it was already initialized. - Top level `TreeMap` segment tooltip was positioned incorrectly after drilling down and back up. - `min`/`max` of `ValueAxis` was not being updated after `invalidateRawData()` call, and series were stacked. - Tooltip sometimes was pointing outside chart container. - `ChordLink` bullets were not properly positioned on init. - `DateAxis` was not working well if `baseInterval.count > 1`. ## [4.0.3] - 2018-11-30 ### Added - Ability to set default locale via `am4core.options.defaultLocale`. When set, all new charts will automatically assume that locale, freeing you from setting locale for each chart individually. - `reverseOrder` added to `Container`. Allows reversing order of its `children`. ### Changed - Moved `Legend` of a `MapChart` from `chartAndLegendContainer` to `chartContainer`. In order to position legend on map chart, use `legend.align` / `legend.valign` properties. - Default value of `showOnInit` on any `Series` is now `false`. Except if you are using "animated" theme, which sets it to `true` by default. ### Fixed - JSON: Using `type: "Sprite"` in JSON config was not creating elements properly. - Initial chart rendering optimized Charts should build faster. - Some more performance optimizations. - Setting `hiddenInLegend` on `Series` after chart was already built had no effect. ## [4.0.2] - 2018-11-28 ### Added - New method `setInterval()` on all base objects added. Works exactly like JS's `setInterval` but is automatically killed when target object is disposed. - Added array utilities to `am4core`. ### Changed - Removed unused `"label"` adapter from `Axis`. ### Fixed - [Issue 588.](https://github.com/amcharts/amcharts4/issues/588) - Fixed mouse wheel and zoom control zooming of a map which does not occupies all the div size. - Fixed map scaling issues of a map which does not occupies all the div size. - Sometimes axis labels were not formatted using number or other formatters. - Adapters of data items were not being copied to clones. - `text` property of `AxisDataItem` was not being copied to clones. ## [4.0.1] - 2018-11-24 ### Fixed - Issues with stacked series and `min`/`max` of `ValueAxis` fixed. - Chart cursor now dispatches `"panning"` event only if moved by at least 3 pixels. This solves problem with panning on click. - If `extraMin`/`extraMax` were set on `ValueAxis`, some unnecessary zoom used to happen. ## [4.0.0] - 2018-11-22 ### Changed - Droping BETA tag! - `DropShadowFilter` will now always use balck by default instead of `"alternativeBackground"` from the theme. ### Fixed - Setting `hiddenInLegend = true` on Series was causing the chart to hang. ## [4.0.0-beta.87] - 2018-11-22 ### Added - Full source code for amCharts 4 is now included under `/src/`. ### Changed - Full language files are now under `/src/lang/`. If you need to make a translation, do a PR on those files/dir. ## [4.0.0-beta.86] - 2018-11-20 ### Fixed - In some situations waiting for `"ready"` event was producing unnecessary frame requests. ## [4.0.0-beta.85] - 2018-11-20 ### Added - `"ready"` event added to `Sprite`. Sprite fires it right after `"init"` event. `Container` fires it when all of its children are ready. - `system.isPaused` property added. Setting it to `true` will effectively pause any chart activity, making them completely static. - `ErrorBullet` class added. Allows drawing error charts. (Check `error-chart` and `xy-error-chart` examples for code samples) - JSON: String-based `cursorOverStyle` and `cursorDownStyle` are not supported. ### Fixed - JSON: Setting `ColorSet` properties `baseColor` or `list` was not working properly. - Accessibility: Legend item was not properly referring to a Series via `labelled-by`. - `Label.wrap` was breaking lines mid-word even if there where words that would fit into alotted space. - Memory leak fixed. - Sometimes `Animation` was not firing `"animationended"` event (when elastic easing was used). ## [4.0.0-beta.84] - 2018-11-18 ### Added - `exportable` (default `true`) property added to `Sprite`. If set to `true` this element will not appear in the exported image of the chart. ### Changed - `exportable` is now set to `false` by default on `Scrollbar` grips, zoom out button. ### Fixed - JSON: `dateFormats` was being ignored. ## [4.0.0-beta.83] - 2018-11-15 ### Added - [`hideOverflow`](https://www.amcharts.com/docs/v4/reference/svgcontainer/#hideOverflow_property) added to `SVGContainer` class. If set to `true` it will apply `overflow: hidden` to chart container so that all chart elements are contained within. Default is `false`, except on `MapChart`, which has it at `true`. ### Fixed - Some adjustments and fixes to animations associated with `hide()`/`show()` functions. - If a legend was initially disabled, it was not appearing when enabled later. - `chart.addData()` was not adding data to `XYChart` scrollbar series. ## [4.0.0-beta.82] - 2018-11-14 ### Added - JSON: `forceCreate` property added. If found in an item of an array, it will force creation of the new object, even if object with same index already exists in target `List`. - French locale. ### Changed - Adjusted animation durations in "animated" theme. ### Fixed - JSON: String-based percent and color values were not being parsed correctly in some cases. - JSON: `HeatLegend` was erroring if its `series` property was referencing to Series by id. - Disposing an item with a custom `id` set was not clearing it from id map properly resulting in errors if item with the same id was being added later. - `SankeyDiagram` was not taking chart's padding into account when sizing itself. - Axis ticks were not being positioned properly after data update. - Map using `deltaLongitude` was being positioned incorrectly. - 3D columns z-indexing was sometimes incorrect. - `PieChart` label placement with custom `startAngle`/`endAngle` was sometimes off. - Label bullets on columns were not being restored from truncated state when width of the columns was increasing. - Series `show()`/`hide()` were using `interpolationDuration` setting instead of `defaultState`/`hiddenState` transition duration when showing/hiding. ## [4.0.0-beta.81] - 2018-11-13 ### Fixed - `chart.hiddenState.properties.opacity` is no longer set to `1` by default. Removed this in order it to be `0` so that charts using animated theme would always fade-in. - Better initial rendering of `ValueAxis` (removed unneeded animations). - Sometimes map was not positioning itself at `homeGeoPoint`. - Map with Eckert6 projection in some cases was not displayed properly. ## [4.0.0-beta.80] - 2018-11-13 ### Fixed - Legend in external container was resulting in infinite loop. - Rendering an arrow on a `MapLine` with same source and destination point was resulting in error. ## [4.0.0-beta.79] - 2018-11-12 ### Fixed - `goHome()` on `MapChart` was not working properly. - `projection` change on `MapChart` was not working properly. ## [4.0.0-beta.78] - 2018-11-11 ### Changed - `DataParser` property `type` was renamed to `contentType` in order not to conincide with JSON-based config built-in keyword `type`. ### Fixed - Some rendering issues fixed. ## [4.0.0-beta.77] - 2018-11-10 ### Fixed - Removed console debug (yes, again). ## [4.0.0-beta.76] - 2018-11-10 ### Fixed - Removed console debug. ## [4.0.0-beta.75] - 2018-11-10 ### Added - You can now use `"{percent}"` placeholder in `tooltipText` of `HeatMapSeries` items. ### Fixed - Draggable/trackable areas of the chart were intercepting all mouse buttons, including right and back/forward. - Fixed `MapChart` issue with dragging map by touch on hybrid devices. ## [4.0.0-beta.74] - 2018-11-08 ### Fixed - `ColumnSeries3D` were broken since last release. ## [4.0.0-beta.73] - 2018-11-07 ### Changed - `axisFills.template.interactionsEnabled` is now set to `false` by default. If you need to attach events on an axis fill, you will need to set it to `true`. ### Added - `autoDispose` property added to `Series` and `Axis` classes with default value `true`. This means that series/axis will be automatically disposed when removed from chart's `series`, `xAxes`, or `yAxes` lists. - It is now possible to have 3D stacked columns (by setting `clustered = false` on series). ### Fixed - If chart container was moved in DOM tree, it stopped sensing resize and was not updating its size anymore. - Sometimes `ValueAxis` could show zero label with a minus sign. - Arrows on `MapLine` were not drawn. - It was not possible to change the text color of the tooltip on `TreeMap` diagram. - `axis.tooltipPosition = "pointer"` was not working as it should - always follow the mouse/pointer. - If series had `data` set directly, it was still using chart's global `data`, resulting in combined datasets and potentially visual anomalies. - Setting `cellStartLocation` did not have any effect on an already inited chart. - Line series could be cut off in the beginning (when zoomed-in closely). - Vertical axis ticks were not being positioned properly if axis had a title. - 3D columns were not using chart's `depth`/`angle`. ## [4.0.0-beta.72] - 2018-11-03 ### Changed - For any `XYSeries` if the `itemReaderText` is not set explicitly, it will automatically try to fill with values from `dataFields`, so that each series element, like a Column has at least rudimentary screen-reader text. ### Fixed - Added in TypeScript 3.x support. - `ColumnSeries` with two category axes anomaly fixed. ## [4.0.0-beta.71] - 2018-11-01 ### Fixed - Calling `dispose()` on a `TreeMap` was causing an error. - Legend items were being duplicated every time its disabled property was reset back to `false`. ## [4.0.0-beta.70] - 2018-10-31 ### Fixed - Keyboard dragging of elements such as scrollbar grips was not working. - "hoverable" elements were not staying "hovered" after tap in Mobile Safari. - `addData()` with more than one data item added was not working well. - Zoomout button was visible on initial animation. - Dynamically changing `Legend.position` was not updating its layout properly. - Vertical axis tick position with rotated labels was incorrect. ## [4.0.0-beta.69] - 2018-10-30 ### Fixed - Some charts were not properly displayed if initialized in a hidden (`display: none`) container, then revealed (`display: block`). - Last slice of the `PyramidSeries` was not visible for certain widths. - Adding `Legend` to a chart that had series with bullets using heatrules was causing an error. - Label rotation was being ignored on `SlicedChart`. - Labels of `PyramidSeries` were not centered (when `alignLabels = false`). - Animation of labels for horizontal `PictorialSeries` was very jumpy. - `position` and `rotation` of labels in `PyramidSeries` was not working properly. - An error was occurring if chart's with a category axis data was updated and it contained less data points than before. ## [4.0.0-beta.68] - 2018-10-30 ### Changed - `tooltip.defaultState.transitionDuration` and `tooltip.hiddenState.transitionDuration` default values of animated theme set to `400`. ### Fixed - Chart was not being drawn properly when instantiated in a hiden container. ## [4.0.0-beta.67] - 2018-10-29 ### Fixed - Chart `Cursor` was preventing hovers on series' elements like columns or bullets. - Mouse cursor's down styles (like on scrollbar) were not being reset back properly in some cases. ## [4.0.0-beta.66] - 2018-10-28 ### Fixed - Axis glitches in `XYChart3D`. - `XYCursor` movement issues. ## [4.0.0-beta.65] - 2018-10-28 ### Changed - `tooltip.hiddenState.transtionDuration` and `tooltip.defaultState.transitionDuration` are now set to 1 (on non-animated theme) to avoid some tooltip flickering. - Individual legend items (label, value label, and marker) now have their `interactionsEnabled = false` set by default to avoid double events. If you need to add events to these particular elements (as opposed to the whole legend item), you will need to set `interactionsEnabled = true` on that element. ### Fixed - Calling `show()` on a `MapSeries` object was resulting in an error. - 3D columns were not visible if their value was zero. - Bullets are now hidden if `minBulletDistance` is set. ## [4.0.0-beta.64] - 2018-10-27 ### Added - `shouldClone` flag added to `EventDispatcher`'s `on` and `once` methods. Can be used to restrict cloning of events when object itself is cloned. - [`showOnInit`](https://www.amcharts.com/docs/v4/reference/sprite/#showOnInit_property) property added to `Sprite`. If this is set to `true`, the `Sprite`, when inited will be instantly hidden ("hidden" state applied) and then shown (animate properties form "hidden" state to "default" state). Animation will take `defaultState.transitionDuration`. `Series`, `Chart` classes has this set to `true`, so that they would perform initial animations. If you want a sprite (chart, series) not to be shown initially, you can set Sprite's [`hidden`](https://www.amcharts.com/docs/v4/reference/sprite/#hidden_property) to `true`. (`setting sprite.visible = true` won't work as expected anymore). ### Changed - If chart rendering takes too long, it now is split into chunks, which makes the browser/page remain responsive even if you have a lot of charts to build. - Changed how pre-hiding Series works. If you want series to be initially hidden, use `series.hidden = true` instead of `series.visible = false`. - Removed `"hold"` and `"rotate"` interaction events and releated options and functionality, since they weren't used anywhere. - Removed `"delayFirstHit"` option from `Sprite.hitOptions`. - `chart.defaultState.transitionDuration` is set to `1`. This allows the chart to appear one frame after init and helps to avoid various flickers that happen while chart is building. Animated theme has this value set to `2000`. ### Fixed - Performance enhancements. - Non-draggable/trackable but otherwise interactive elements of the chart no longer prevent scrolling and other gestures on touch screens. - `PieSeries` labels sometimes were positioned incorrectly (using non-default start/end angles). - Slices (also columns of `RadarChart`) were not drawn if `radius <= 0` (even if `innerRadius > 0`). This resulted in radar columns not rendered in some cases. - `MapChart` was not resizing properly when div size changed. - `PictorialStackedSeries`, while `containerdiv` was resized did flicker a lot. - If a Tooltip is visible while its Sprite changes size/position, it updates its position as well. - Setting `chart.data = []` was not clearing data properly. ## [4.0.0-beta.63] - 2018-10-20 ### Fixed - In some cases a `PieChart` could overlap its legend. - `PieChart` flicker after `invalidateData` fixed. - An error was occurring when data was updated on chart with series with bullet while hovering it with cursor. ## [4.0.0-beta.62] - 2018-10-19 ### Fixed - Tooltip issue fixed. ## [4.0.0-beta.61] - 2018-10-19 ### Changed - If element has `url` set, when clicked, it will now parse for data placeholders in curcly brackets, e.g. `"{category}"` allowing have dynamic data-driven URLs. Note, the elements are not url-encoded so you need to specify encoding manually, e.g.: `series.columns.template.url = "https://www.google.com/search?q={category.urlEncode()}";`. ### Fixed - `Label.fullWords = false` was not working properly. - `AxisLabelCircular` was positioning labels incorrectly, if label.radius was negative (since 59). - `"grid"` layout in `Container` was incorrectly layouting elements if their `width` was set in percent. - [IE] Multi-line truncated labels were not working properly on IE. - [IE] was incorrectly zIndexing elemens (since version 56). - [IE] tooltip initial flicker solved. - [IE] was incorrectly sorting multiple series tooltips (if `Cursor` was used). ## [4.0.0-beta.60] - 2018-10-18 ### Changed - `"hidden"` data field added to series' `dataFields`. Removed `"visible"` data field from `PercentSeries`. You should use `"hidden"` data field to set which slices/columns/etc. are hidden initally. - `AxisLabelCircular`'s `radius` can now be set in `Percent`. `PieChart`'s label radius default value was set to `5%`. ### Fixed - Multi-line labels were not being aligned properly in IEs. - In some cases, `fillModifier` was not applied if set after `fill`. - In some cases, a chart with `seriesContainer` disabled, or when `seriesContainer`'s height/width was 0, could produce a JS error. - Some performance tuneups, especially for charts with axes and more data. ## [4.0.0-beta.59] - 2018-10-17 ### Added - [`widthRatio`](https://www.amcharts.com/docs/v4/reference/image/#widthRatio_property) and [`heightRatio`](https://www.amcharts.com/docs/v4/reference/image/#heightRatio_property) properties on `Image`. ### Fixed - Some adapters for Axis elements were being applied twice. ## [4.0.0-beta.58] - 2018-10-17 ### Added - `ExportMenu`'s "custom" items can now have `"callback"` which is a function to call when clicked on such custom item. ### Changed - Slice labels on a `PieChart` now move with the slice (if `alignLables = false`). ### Fixed - `requestAnimationFrame` now is called only when needed. This reduces idle CPU usage. - Fixed `m4core.color()` result caching issue. - Charts were broken in IEs since beta.57. - `Tooltip` on `LineSeries` was not updating color if segment changed color. - `MapChart` without any series was displaying an error in console. - Axis tooltip was trimmed when `renderer.inside = true`. - `StepLineSeries` `startLocation`/`endLocation` bug fixed. - `"hover"` state was not being applied to series' bullet if it did not hav `tooltipText` set. - `bulletLocation` for horizontal `ColumnSeries` fixed. - Value labels of `Legend` were not in correct positions if `Legend` was positioned at the top or bottom (too close to legend label). ## [4.0.0-beta.57] - 2018-10-15 ### Changed - All charts (that inherit from `Chart`) now will apply "hidden" state right after they are validated, then immediately "default" state. This allows creating initial animations such as fade-in (if using animated theme). All you need to do is set: `chart.hiddenState.properties.opacity = 0;`. ### Fixed - Mouse wheel zoom was broken since beta.56 on `MapChart`. - Pushing `Sprite` to `Container.children` directly (instead of setting parent) used to produce a JS error. ## [4.0.0-beta.56] - 2018-10-12 ### Added - New `Sprite` adapter: `"populateString"`. Applied to strings after `Sprite` replaces data binders with real values, but before any formatting by `Label` kicks in. - New `Label` property: [`ignoreFormatting`](https://www.amcharts.com/docs/v4/reference/label/#ignoreFormatting_property). If set to `true` will treat formatting blocks in square brackes (e.g. `"[red bold]"`) as regular text and will display them as such. ### Changed - Default big, small, and byte suffixes in `NumberFormatter` are now translatable via locale files. - The suffix for thousands "kilo", was changed to lowercase "k", as per [standards](https://en.wikipedia.org/wiki/International_System_of_Units#Prefixes). - On `XYChart`, default for [`mouseWheelBehavior`](https://www.amcharts.com/docs/v4/reference/xychart/#mouseWheelBehavior_property) changed to `"none"` (was `"zoomX"`). ### Fixed - Improved performance! All charts types are now noticably, some drastically are faster. Some memory leakages fixed as well. - Now `MapPolygonSeries` will not inherit chart's global `geodata` if it has own `geodataSource` set. - `DateFormatter` was not parsing all AM/PM string dates correctly. - `DateFormatter` was not parsing `MMM` (short month names like "Jan", "Feb") propertly. - In-line date formatter was not working correctly in some cases, e.g. `"{dateX.formatDate()}"`. - Setting `chart.mouseWheelBehavior = "none"` did not release wheel scrolling of the web page when hovering over chart. - `DataSource`'s' `"done"` event was being called if parsing of loaded data failed. Not anymore. `"done"` is called only on successful load. To catch any load (including one that ended in http or parse error) use `"ended"`. - `DataSource`'s' `reloadFrequency` was broken if error occurred during one of the loads. This has been fixed. Even if error occurrs, loader will try to reload data in the next reload slot. - JSON: `heatRules` did not work properly with their target set to a list template, e.g. `mapPolygons.template`. - Auto-calculated `DateAxis.baseInterval` was not being carried over to the `XYChartScrollbar`. - `DurationAxis` scale sometimes was dropping to negative values, even there were no negative values in data. - `PieChart` and `Legend` were not working properly with `chart.zoom()` or `legend.zoom()` methods. ## [4.0.0-beta.55] - 2018-09-26 ### Added - New series type suitable for `SlicedChart`: `PictorialStackedSeries`. (check `pictorial-stacked-chart` and `pictorial-stacked-chart-horizontal` demos) - New themes: "dataviz", "moorisekingdom", "frozen", "spiritedaway". - New Chart property: `logo`. If you are using amCharts with a free license, it holds reference to amCharts logo. Use it to position logo with `align` and `valign` properties. - New `FunnelTick` properties: `locationX` and `locationY`. Allow specifying a relative location within target element where tick is pointing to. ### Changed - `FunnelChart` was renamed to `SlicedChart`. The previous name did not correctly represent capabilities of the chart type that can display not only funnel series, but also pyramids and stacked pictorial series. `FunnelSeries` remains as it was before. ### Fixed - Mouse wheel zoom was extremely slow in FireFox. - Sometimes colors duplicate colors were generated by `ColorSet`. - HTML-based labels were not accounting for "pixel ratio" on Retina displays, making tooltips larger then they are supposed to be. ## [4.0.0-beta.54] - 2018-09-22 ### Fixed - Chart Cursor was working only for the first chart on the same page. - `CSVParser` was not parsing `dateFields` and `numberFields` correctly. - Issues with labels rendering in incorrect position fixed. - `LinearGradientModifier` was not copying gradient properties to clones (since last version only). - `FunnelSlice` sometimes rendered slice edges with no anti-aliasing. - When calculating area of the Pyramid slices height of `sliceConnector` was not being taken into account. - Reset `label.renderingFrequency` back to `1` to solve some unwanted label flickering. - `MapImage` items were not showing if added via `series.data` (since last version only). ## [4.0.0-beta.53] - 2018-09-21 ### Added - New property `durationFormat` on `DurationFormatter`. If set, it will force this format to be used, instead of one determined by `baseUnit`. ## [4.0.0-beta.52] - 2018-09-21 ### Added - `CurvedColumnSeries` added. Allows having columns as curves or as triangles. Check `curved-column-chart` and `triangle-column-chart` in examples folder. - `RadialGradientModifier` class added. Allows building more donut-like pie charts. Check `semi-circle-donut-chart` in examples. - New chart type: `FunnelChart`, which can show regular FunnelSeries and PyramidSeries. - New axis type: `DurationAxis`. Values on it are treated and formatted like time durations. - `extraMin` and `extraMax` properties added to `ValueAxis`. Can be used to relatively adjust calculated minimum and maximum scale values. - Two new read-only properties added to `Container`: `contentWidth` and `contentHeight`. Will hold width/height in pixels of the actual dimensions of elements in Container. ### Changed - `DurationFormatter` now uses `TimeUnit` for its `baseUnit`, rather than arbitrary codes. - `durationFormat` property was removed from `DurationFormatter`. Use [`getFormat()`](https://www.amcharts.com/docs/v4/reference/durationformatter/#getFormat_method) method to get correct format instead, then pass in to `format()`. - Series will not show a tooltip (if one axis is `CategoryAxis`) if there is no value for this category (used to show tooltip if it had some extra text). ### Fixed - Legend `valueLabel` values were not shown on chart initial render. - 3D pie slices were not showing full stroke, only on the upper part of a slice. - Sometimes `XYChart` did some additional animation even after all series finished animating, causing zoom-out flashing briefly. - `XYChartScrollbar` was not showing series if data to the original series was added later (or changed). - Chrome was not showing line series in `XYChartScrollbar` if all values were equal. - Creating an empty line (without `multiGeoLine` set) was resulting in critical error. ## [4.0.0-beta.51] - 2018-09-13 ### Changed - Changed `Label.renderingFrequency` to `2`, for better performance. ### Fixed - Performance tweaking. - `DateAxis.baseInterval` was ignored in JSON-based configs. - `"hoverActive"` state was not always being correctly applied. - Better handling of cursor zoom and pan when outside chart area. - Fixed occasional error when formatting dates or numbers. - Line chart starts new segement only if properties (like `stroke`, `fill`, `strokeDashArray`, etc.) in data have changed. It used to start new segment if properties in data were defined resulting in reduced performance and disabled smoothed lines. - Labels were not updating their position if their `fontSize` changed. - `Sprite.nonScalingStroke = true` was ignored if set after `Sprite.strokeWidth`. - `LineSeries` could leave some garbage lines while zooming. - `ColumnSeries` could leave some garbage columns while zooming. - `DateAxis` with one date only in chart data was not rendered properly. - The chart was not zooming out after data validation. - Added `ghostLabel` to `Axis` which is an invisible label and it helps to avoid unwanted changes of axis widht/height when the scale changes, e.g. on zoom. - `zoomToMapObject`, if used with `MapPolygon` and custom `zoomLevel` was not working properly. - `"hidden"` event of Series was called on initial chart initialization. ## [4.0.0-beta.50] - 2018-09-10 ### Added - `am4core.unuseAllThemes()` method added. Any chart created after this method call will not have any theme applied to it. - New property `am4core.registry.baseSprites` will now hold all active (non-disposed) instances of top-level elements, such as charts. - `startLocation`/`endLocation` properties added to `CategoryAxis` (previously available on `DateAxis` only). Allows to specify location the first and last cells of the axis should start on respectively. - `innerRadius` of a Slice can now be set as `Percent` (e.g. `am4core.percent(50)`). - You can now set custom radii (`radius` property) on Pie series (if you have more than one, you might want one to be larger and another smaller). ### Changed - [`MapLine.imagesToConnect`](https://www.amcharts.com/docs/v4/reference/mapline/#imagesToConnect_property) now accepts an array of string IDs that can reference images by their `id` property. - Changed `tooltip` inheritance so that it checks for `virtualParent` rather than direct `parent`. E.g. series' bullets use series' tooltip and not chart tooltip as it was before. ### Fixed - Map polygon stroke thickness could be rendered incorrectly when zooming quickly. (Issue #175) - Calling `addData()` more than once before data was validated resulted only last data item to be added. (Issue #222) - `DateAxis.baseInterval` was ignored if data was set directly on series. - `MapLine` was not paying attention to the properties set on template. - `HeatLegend` was not updating its label count after its size changed. This could have been resulting in very few labels if initial container (div) size was small. - The map portion of `MapChart` was incorrectly positioned after container (div) resize. - Object properties, like `"name"` in GeoJSON were overriding same properties in `MapSeries` data. Now, the values specified in data are used over ones in GeoJSON. (Issue #307) - Axis ranges used to reset `axisRange.label.text`. (Issue #308) - Fixed issues with disposing series and charts. - Updated to [canvg 1.5.3](https://github.com/canvg/canvg/releases/tag/v1.5.3) to fix em/rem text issue for epoxrt fallbacks. ## [4.0.0-beta.49] - 2018-09-05 ### Added - JSON config: added `callback` property, which if it holds a reference to function will call it within the scope of the object being prepared. - Adapters for `url` and `urlTarget` properties. - Chart can now be panned or zoomed using mouse wheel. To set what it does use `mouseWheelBehavior` on `XYChart` (see next point) - [`mouseWheelBehavior`](https://www.amcharts.com/docs/v4/reference/xychart/#mouseWheelBehavior_property) added to `XYChart`. Options: `"zoomX"` (default), `"zoomY"`, `"zoomXY"`, `"panX"`, `"panY"`, `"panXY"`, `"none"`. - [`mouseWheelBehavior`](https://www.amcharts.com/docs/v4/reference/mapchart/#mouseWheelBehavior_property) added to `MapChart`. Options: `"zoom"` (default), `"none"`. ### Changed - Second parameter to `Cursor`'s [`triggerMove()`](https://www.amcharts.com/docs/v4/reference/cursor/#triggerMove_method) method was changed from boolean to enumeration of "stickiness" level: `"hard"`, `"soft"`, `"none"` (default). ### Fixed - Error fixed when `Popup` object was being disposed. - Over-panning of an `XYChart` did not disappear after mouse button was released outside chart. - Multiple memory leaks fixed. - `MapChart` was rounding lat/long coordinates too much which was resulting in pixelated maps for small-area maps. ## [4.0.0-beta.48] - 2018-08-31 ### Added - `useWebFonts` setting in `Export`. Allows disabling of download of web fonts when exporting. - `useRetina` setting in `Export`. Images are now exported scaled up on retina displays by default. Set `useRetina = false` to disable. ### Changed - Export fallback mechanism for older browsers changed from FabricJS to canvg, which is much lighter and has better text formatting support. - On retina displays images will now export supersized in order not to lose quality. Set `useRetina = false` to disable. - amCharts logo will now auto-hide on supersmall chart sizes. ### Fixed - Cursor was zooming the chart even if drag motion was performed on an external element positioned over the chart. - Cursor was not hidden when it was no longer hovering the chart area if chart had no padding. - `urlTarget` was not carried over from `ListTemplate` template to new items. - Cursor could cause chart to freeze up on a DateAxis with empty cells in the axis' beginning or end. - Export will now correctly handle web fonts, such as Google Fonts. Please note that FontAwesome is not supported, since they forbit any kind of usage, except inclusion via CSS. ## [4.0.0-beta.47] - 2018-08-24 ### Added - New series type: `OHLCSeries`. - `goHome()` method added to `MapChart`. Calling it will reset map to `homeZoomLevel` and `homeGeoPoint`. - `homeGeoPoint` added to `MapChart`. Allows setting initial `geoPoint` at which map will be centered. - `homeZoomLevel` added to `MapChart`. Allows setting initial `zoomLevel`. - `maxPanOut` property added to `MapChart`, with default value `0.7`. It prevents map to be dragged out of the chart area. - `noRisers` property added to `StepLineSeries`. It allows step line chart without vertical (or horizontal, depending on orientation) lines. - Step line without risers now allows making Waterfall chart. Example added. - `startLocation` and `endLocation` added to `StepLineSeries`, that allow controling locations at which step should start/end. - `maxPrecision` added for `ValueAxis`. Use it to restrict Value axis to show value labels with less than desired precision (set 0 if you only want integers). - Portugese (Portugal) translation added. ### Changed - `Cursor` will now not move if there's some element obstructing the chart's plot area, e.g. a popup or some other element outside the chart. ### Fixed - Series' and axes' tooltips will now correctly inherit formatters. - Errors when hovering mouse cursor over open Modal. - JSON: `children` property of `Container`-type objects was not being processed correctly. - Popup/Modal now sets `aria-label` automatically if title is set. - Removing bullet template from series or disposing it will remove/dispose all the bullets created from it. - Tooltips were overlapping each other, fixed for the most part, but might still be some situations where they overlap. - Changing data for `MapImageSeries` and `MapLineSeries` used to result runtime error. ## [4.0.0-beta.46] - 2018-08-19 ### Fixed - `TreeMap.homeText` was not working. - `TreeMap` used to display upper level bullets/labels when drilled-down. - `TreeMap` had issues with hiding items using legend (when not using animated state). - Chart cursor was not visible if data was set directly on axis/series but not on chart. ## [4.0.0-beta.45] - 2018-08-17 ### Added - New hardcoded `Sprite` state name added `"hoverActive"` which (if defined) is applied on active elements on hover. This state is applied last in the chain. - New property on `DataSource`: `keepCount`. If set to `true` incremental updates will remove data items from the beginning of the current dataset, when adding the newly-loaded ones. - New property on `DataSource`: `incrementalParams`. It's an object whose key/value pairs will be added to URL as parameters when DataSource is making an incremental load request. - `Popup` (and `Modal`) now have an event dispatcher (`events`) with two events: `"opened"` and `"closed"`. ([more info](https://www.amcharts.com/docs/v4/concepts/popups-and-modals/#Event_handlers)) ### Changed - Legend now respects `itemContainers.template.togglable = false`, which disables default functionality of toggling items when clicked in legend, allowing users to attach their own funcitonality to legend item clicks. - Toggling of items in Legend can now be disabled by setting `chart.legend.itemContainers.template.togglable = false`. - In `XYChart` with a `DateAxis`, cursor and data at irregular intervals will now display a Tooltip for nearest available series' data item. - `zoomToCategories` method of `CategoryAxis` now zooms to the end of the "to" category. - Default `urlTarget` of amCharts logo is now `"_blank"`. ### Fixed - In `DataSource` the formatters `inputDateFormat` was ignored. - Incremental data load via `DataSource` was not working. - Tooltip used to flicker ar 0,0 position in some cases when hovering over elements. - Fixed issue which caused chart to gradually shrink to invisibility under some conditions. - Fixed rendering errors for charts that were initialized in hidden containers. - `XYCursor` lines and axis tooltips were not shown if chart did not have any data (data was set directly on axis/series). ## [4.0.0-beta.44] - 2018-08-14 ### Added - `TreeMap` now supports legend. Legend will be displayed if a) `TreeMap` data is at least two levels deep (legend displays items from a second level); b) `chart.maxLevels` is set to `2` (without setting it no second-level series are created so legend does not have anything to build itself from). [More info](https://www.amcharts.com/docs/v4/chart-types/treemap/#Legend). - Swedish translation. ### Changed - `DateFormatter` will now automatically capitalize month/weekday name if it's the first (or only) word in resulting formatted date. This can be turned off by setting formatter's [`capitalize`](https://www.amcharts.com/docs/v4/reference/dateformatter/#capitalize_property) to `false`. ### Fixed - Removed `@deprecated` commented out methods/properties that were confusing tslint. - Issue that caused the chart to shrink was fixed. ## [4.0.0-beta.43] - 2018-08-12 ### Changed - `$net.load()` options parameter now supports `responseType`. If set to `"blob"` will return response as `Blob` object in `result.blob`. ### Fixed - Value axis min/max calculation algorithm adjusted. Fixed an issue with `strictMinMax = true` and issue with min/max when axis size was very small. - Export now correctly uses external fonts included via `@import`, such as Google Fonts. - Non-clickable columns in `ColumnSeries` will no longer gain focus on click/tap, unless its `hitOptions.noFocus` is set to `false`. - Noon was incorrectly formatted as "AM", instead of "PM". - `TextFormatter` was producing invalid `style` value on empty formatting blocks (`"[]"`). - `parent` was not being set for a `Sprite` that was pushed directly to `Container.children`. - If axis labels were disabled, ranges labels were not visible. - Axis used to reset some of the user-set values when initing renderer, e.g. `dateAxis.renderer.grid.template.location = 0.5` was not working. - `XYChart` with category axis + date axis was not working properly. - Stacked chart with logarithmic axis was not working properly. - JSON: local formatter instances were not being instantiated properly, so all children objects were reusing chart's main formatters. - JSON: Patterns are now supported. ## [4.0.0-beta.42] - 2018-08-05 ### Fixed - Updated default Popup CSS to eliminate a rare scrollbar flashing issue. - Fixed an error with PDF exporting. ## [4.0.0-beta.41] - 2018-08-03 ### Added - `MapSeries` now has `geodata` and `geodataSource`. This allows setting separate maps to each separate map series, which no longer rely on single chart-wide `geodata`. Also, setting `geodata` for `MapSeries` will automatically set `useGeodata = true`, so no need to set it manually. ### Changed - Removed unused `boldUnitChange` from `DateAxis`. - Labels on `DateAxis` will now pay attention to `label.location` if label represents full time period between grids. It no longer will force labels to be in the middle. - `label.currentText` is now public. ### Fixed - Fixed parsing of string dates in ISO format (`"i"`). - Legend marker was not aligned with the text (when marker was smaller). - Solved legend error which happens if you show/hide series after series was added/removed. - Dynamically adding series was not automatically adjusting axis scales. - Vertical `CategoryAxis` was not paying attention to `grid.location`. - Map issues at `minZoomLevel < 1` fixed. ## [4.0.0-beta.40] - 2018-08-02 ### Added - German translation. (de_DE) ### Changed - [`XYChart.getUpdatedRange()`](https://www.amcharts.com/docs/v4/reference/xychart/#getUpdatedRange_method) method is now public so you can use it to recalculate absolute axis range into a relative that takes current zoom and inversion into account. - `Language` now supports `null` in translations which means an empty string. - Interface `iColorSetStepOptions` was renamed to `IColorSetStepOptions` to maintain consistency. - Interface `ColorPurpose` was renamed to `IColorPurpose` to maintain consistency. - `FlowDiagramNode` `value` property renamed to `total`, added `totalIncoming` and `totalOutgoing` properties which hold sum of all incoming/outgoing links. - Removed aliases `startCategory`, `startValue`, and `startDate` from Axes data items. (use `category`, `value`, and `date` respectively) ### Fixed - Improved performance of Sankey/Chord Diagrams. - Elements of `TreeMapChart` were not respecting locale. - Fixed-height bars were drawn incorrectly. - Pre-hidden series were not taken into account when calculating min/max of value axes in some cases. - Setting chart data with less data items then there were before resulted in an error. ## [4.0.0-beta.39] - 2018-07-27 ### Added - `useChartAngles` added to `AxisRendererCircular`. If set to `false` allows to set `startAngle`/`endAngle` to each circular axis individually. ### Fixed - Fixed problem with custom `Legend` data and initial visibility, you can now use `visible: false` to pre-hide custom legend items. - Grid Layout fixed, affects Legend. ## [4.0.0-beta.38] - 2018-07-26 ### Fixed - Using `PieSeries` data field `"visible"` was not graying out Legend's marker. ## [4.0.0-beta.37] - 2018-07-26 ### Added - You can now make series initially to be hidden by setting `series.visible = false`. - `visible` added to `PieSeries.dataFields`. It allows making some of the slices initially hidden. ### Changed - Sankey/Chord diagrams has now toggling nodes enabled by default. To disable, set `chart.nodes.template.togglable = false`. ### Fixed - Text formatter now correctly escapes double square/curly brackets, as well as empty formatting blocks `[]`. - Setting `series.visible = false` or `series.hide()` wasn't toggling off related item in Legend. - Setting `isActive` did not affect `Container`'s background (assuming it had `"active"` state). ## [4.0.0-beta.36] - 2018-07-25 ### Added - `elements` property in `Popup`. Returns an object consisting of references to various elements of the Popup, like content block, close button, etc. ### Changed - `am4core.getSystem()` has been changed to `am4core.system` ### Fixed - Fixed double "amcharts" in Popup's class names. - Fixed dragging on of absolute-positioned Popups. - Escaping square brackets in text (by repeating them twice) was not working. - Fixed a lot of disposer leaks. - Fixed an issue that caused runtime errors with Rollup. ## [4.0.0-beta.35] - 2018-07-23 ### Added - New adapter on `Component` (and everything that inherits it including charts and series): `"data"`. - New adapter on `Popup`: `"closable"`. ### Changed - `showModal()` and `hideModal()` methods were renamed to `openModal()` and `closeModal()` respectively. - `show()` and `hide()` methods on `Popup`/`Modal` were renamed to `open()` and `close()` respectively. ### Fixed - More performance-related improvements, especially with `CategoryAxis`. - Changing `interactionsEnabled` from `false` to `true` was not working properly in IE. - Setting `axisRenderer.inside = true` after chart was already built didn't work. - `zoomlevelchanged` event of `MapChart` was being fired even if zoom level did not change. - Setting `MapChart.deltaLongitude` was ignored if it was set before projection was set. - Map tooltip bounds were not being updated when map container's size changed. ## [4.0.0-beta.34] - 2018-07-22 ### Fixed - Dramatic performance improvements! ## [4.0.0-beta.33] - 2018-07-19 ### Added - `calculatePercent` flag added to `Series`. Default value is `false`, except for `PieSeries`. Series will not calculate percent values of each data item if this is not explicitly set to `true`. Since it wasn't been used anywhere but Pie chart, this should improve performance of initial data parsing. ### Fixed - Performance improvements. Especially when zooming/scrolling chart with a lot of data. - `lineSeries` was not paying attention to `propertyField` values set in data. - Radar and Gauge charts were not centered properly when resizing window. - Container's background properties were not copied when cloning container. ## [4.0.0-beta.32] - 2018-07-17 ### Important (potentially breaking changes) - To maintain event-naming consistency, events `"insert"` and `"remove"` were renamed to `"inserted"` and `"removed"` respectively in `List` and its inheriting classes. [#132] - To maintain event-naming consistency, events `"clear"` and `"remove"` were renamed to `"cleared"` and `"removed"` respectively in `Dictionary` and its inheriting classes. ### Fixed - Significant performance improvements were made. - JSON config: Filters could not be used. - Some properties were not being copied when cloning objects, e.g. `segments` in `LineSeries`. (`interactionsEnabled` and some others) - Circular axis was not properly drawing grid lines if `radius` was < `percent(100)`. - `Button` label was "stealing" interactions from the button itself. - `Tooltip` was sometimes drawn without pointer if "animated" theme was not enabled. - Fixed label alignment of Y axis. ### Changed - Improved `contentAlign` (when content size is bigger than actual size of a container). ### Added - Two new adapters added to `Label`: `"textOutput"` and `"htmlOutput"`. Both are applied **after** label contents (text or HTML respectively) are populated with data. - Added `"custom"` option to export menu types, which now allows creating clickable custom items in the `ExportMenu`. - `Legend` now accepts "raw" data, enabling creating custom items: `legend.data = [{name:"name 1", fill:"#ff0000"}, {name:"name 2", fill:"#00ff00"}]`. Important: a legend with custom items must be added to some chart container manually (e.g. `chart.chartContainer`). Assigning it to `chart.legend` will overwrite its data. ## [4.0.0-beta.31] - 2018-07-06 ### Important - Layouting mechanism was revamped to make it more consistent and intuitive. If you see some layout issues with your chart, please let us know! ### Added - New chart type: [`ChordDiagram`](https://www.amcharts.com/docs/v4/chart-types/chord-diagram/). ### Changed - The `Adapter` `keys` property is now a 0-argument function and not a property. - `Adapter` callback now has third parameter `key`, which is a string indentifier of the adapter being applied. - `ChordDiagram`, same as `SankeyDiagram` now extend `FlowDiagram` class. `FlowDiagram` can not be instantiated alone, it's a base class for those two. - `minWidth`/`minHeight` is now set to some small amount on a `PieChart` so that it remains visible even, if the oversized legend does not fit into container. - `heatRules` no longer override properties if they are set using `propertyFields`. ### Fixed - Printing in Firefox was broken after latest updates in export/print. - Re-enabled data export on legacy IEs. - If a legend was initially disabled, it did not show up after enabling it later. - Series tooltip was not disposed when series was disposed. This could result in tooltips hanging and not hidin in such charts as `TreeMap` after data was changed. - `Tooltip` was sometimes flickeing at 0,0 position when first hovered on columns of a series. - When all values were 0, `XYChart` was not displayed properly. - When all values were equal and less than 0, `XYChart` was not displayed properly. - Zero-value slices were shown as black rectangles in the pie chart legend. - Labels were not showing tooltips. - `LineSeries` was not displayed properly if colors were set in data. (using `propertyFields`) - Tooltips were shown with white background when first hovered over slices/columns/etc. - Setting `interactionsEnabled = true` did not if it was set to `false` previously. - `axisFill` was not showing `innerRadius` correctly if it was set as `Percent`. - Data update on `SankyDiagram` was resulting in error. ## [4.0.0-beta.30] - 2018-06-22 ### Fixed - JSON config: `heatRules` can now refer to bullets in `tartget` using syntax `"bullets.0.property"`, e.g. `"bullets.0.circle"`. (meaning use "circle" property of the first bullet as heat rule target) - Export: fixed SVG export on Firefox. - Export: fixed SVG/CSV/JSON export for Edge/IE. - Export: fixed sheet name limitations for Excel export. - Export: print option was printing the whole page instead of just chart on IEs. - Export: fixed bitmap image export on IEs. - [Issue 65.](https://github.com/amcharts/amcharts4/issues/65) ### Changed - `class` attribute is no longer applied to elements by default. To enable it use new setting `am4core.options.autoSetClassName`. - `class` attributes now will contain the whole inheritance chain, e.g. `"amcharts-Sprite amcharts-Container amcharts-Button"`. Class names are no longer lowercased. - The `svgContainer` property is now an `SVGContainer`, not an `HTMLElement`. ### Added - New global option `am4core.options.autoSetClassName` (default `false`). If set to `true` will set `class` attribute of all elements that reflect class element was created in, including inheritance, e.g. `"amcharts-Sprite amcharts-Container amcharts-Button"`. ### Removed - Element-level `classNamePrefix` is no longer available. Use global `am4core.options.autoSetClassName` instead. ## [4.0.0-beta.29] - 2018-06-16 ### Fixed - Wrong `Cursor` behavior in Edge browser on hybrid touch screens. - Malfunctioning colors in IE9. - Console errors, triggered by mouse hover in IE9. - A bunch of errors and bugs on Popup/Modal in IE9. - Enabling `ExportMenu` on IEs was breaking the chart. - `"dragstop"` event was not being triggered on touch and hybrid devices. ### Changed - Dramatically improved performance of dragging of Popup. - The `dataItem` of the tooltip is now set sooner, which enables it to be used in its various adapters. ### Added - `Sprite` now has [`hoverOptions`](https://www.amcharts.com/docs/v4/reference/sprite/#hoverOptions_property) which can be used to set up how touch "hovering" works. ## [4.0.0-beta.28] - 2018-06-05 ### Fixed - Using chart `Cursor` now prevents default browser gestures on touch and hybrid displays. - Disabling elements (e.g. Legend or Axis labels) will now make other elements take up vacant space automatically. - Tooltips on `XYSeries` data items with zero value were not being shown. - Sometimes `XYSeries` tooltips were messed up and shown in incorrect position. - Updating chart data with stacked series could result incorrect min/max values on `ValueAxis`. - `Treemap` was not showing all the required levels on zoom-out unless animated theme was being used. - Sometimes unpredictable behavior of labels on a logarithmic value axis was fixed. - `DateAxis` with `skipEmptyPeriods = true` was showing axis tooltip at incorrect positions in some cases. ### Changed - `Sprite.mouseEnabled` was renamed to `interactionsEnabled`. - An option `"mouse"` for `tooltipPosition` was renamed to `"pointer"`. ## [4.0.0-beta.27] - 2018-06-01 ### Fixed - Issue with `Label` text truncation. - Huge performance improvements, especially on initial chart load. - `Animation.resume()` was not working. ### Changed - Default `tooltipLocation` on `SankeyLink` is now `0.5`. - Default value of `series.hiddenState.opacity` is now `0` (was `1`). Animated theme sets it to `1`, because it animates stuff by interpolation, rather than fade. ### Added - `pt_BR` and `en_CA` locales. - `fullWords` property on `Label`. Works only when `truncate = true`. Setting to `false` will force non-fitting label to be truncated in the middle of the word. ## [4.0.0-beta.26] - 2018-05-30 ### Fixed - Error with `EventDispatcher is disposed`. - Having "stray" axis objects (not attached to any chart) was resulting in critical error. - Zooming was broken on `RadarCursor` since last update. - `PieSeries.legendSettings` were being ingored. - `Cursor` was incorrectly doing `panY` (inverted). - Date axis tooltip was not rounding dates to `baseDuration`. - Date axis was not working properly with `min`/`max` values set. ### Changed - Redone chart print functionality. Now printing is done via `
