- Add choose selection callback to remember what attribute index was selected ([#104](https://github.com/GIScience/Leaflet.Heightgraph/issues/104)).
- Add `selectedAttributeIdx` to options to allow choosing a different attribute index than 0 ([#105](https://github.com/GIScience/Leaflet.Heightgraph/issues/105)).

## v1.3.3 (2020-10-21)

## v1.1.0 (2020-07-05)

**Added**
- `graphStyle` option to customize the graph style ([PR #85](https://github.com/GIScience/Leaflet.Heightgraph/pull/85))
- `expandControls` option to hide the close button and expand by default ([PR #82](https://github.com/GIScience/Leaflet.Heightgraph/pull/82))

**Changed**
- `addData` method functionality ([#37](https://github.com/GIScience/Leaflet.Heightgraph/issues/37)):
    - instead of removing and adding the whole height graph only the data
    is cleared and replaced, keeping the L.control.heightgraph instance

    initialization of the height graph

[boldtrn](https://github.com/boldtrn)).

## 0.1.3 (2019-07-17)

**Improvements**

* Allow customizing x and y axis ticks
([#61](https://github.com/GIScience/Leaflet.Heightgraph/pull/61) by

## 0.1.2 (2019-07-17)

**Improvements**

* Callback for the expand state
([#58](https://github.com/GIScience/Leaflet.Heightgraph/pull/58) by

## 0.1.1 (2019-07-17)

**Improvements**

* Allow defining translations for labels
([#53](https://github.com/GIScience/Leaflet.Heightgraph/pull/53) by

**API Changes**

* The width and height of the heightgraph now define the size of the heightgraph,
and not the size of the heightgraph+margins.
You might want to updated your height and width values
([#43](https://github.com/GIScience/Leaflet.Heightgraph/pull/43) by
[boldtrn](https://github.com/boldtrn)).
* The dependencies were refined, if you were using the plugin before,
you might want to recheck that you are using the correct dependencies.
