Adds shortcodes to easily add line, pie and bar charts to your pages using the Flot library.

== Description ==
This plugin adds shortcodes for line, pie and bar charts, created with the Flot javascript library.

For more information on Flot: http://www.flotcharts.org/

= Usage =

Set a custom field 'flot' to 'yes', so the plugin knows to load the required javascript. If you wish you can add these files to your theme on all pages, so this step is not needed. It isn't automatically loaded to reduce page size.

Use the [linechart], [piechart] or [barchart] shortcodes, with the data enclosed between the tags (see example). You can further change the appearance of your chart by using a number of attributes, a full list of which can be seen [here](http://www.youssouhaagsman.nl/wpflot/index.htm#attributes "WP Flot").

**Linechart example:**

`[linechart minx="1950" maxx="1965" miny="0" maxy="100" steps="false" fill="true" points="false" legend="true"]
	       { label: "Series 1",
		data:	[[1963, 43],
				[1959, 48],
				[1956, 50],
				[1952, 30]]
},
	{
		label: "Series 2",							
		data:
			[[1952, 30],
			[1956, 49],
			[1959, 49],
			[1963, 50]] }
[/linechart]`

**Pie chart example:**
`[piechart donut="0.5"]
{ label: "Series1",  data: 10},
		{ label: "Series2",  data: 30},
		{ label: "Series3",  data: 90},
		{ label: "Series4",  data: 70},
		{ label: "Series5",  data: 80},
		{ label: "Series6",  data: 110}
[/piechart]`

**Bar chart example:**
`[barchart]
{ label: "Bars",
data:	[[1, 6],[2, 4],[3, 5],[4, 6],[5, 14],[6, 5],[7, 12]] },
{ label: "More bars",
data:	[[1.5, 3],[2.5, 3],[3.5, 15],[4.5, 3],[5.5, 10],[6.5, 11],[7.5, 10]] }
[/barchart]`
Please note that in Flot, a bar chart reacts like a line chart. If you have two data series with similar positions on the x-axis, they will overlap instead of showing side by side. Also, you both values need to be a number, no text.

== Installation ==
Upload the plugin to your /wp-contents/plugins/ directory, then activate via the plugin menu.

== Frequently Asked Questions ==

= My chart doesn't show up =

* Make sure your data doesn't contain any errors, such as a misplaced comma. The web inspector of your browser can help you with this.
* Check the source of the page, if the javascript contains an html tags, such as p or br, there probably is a problem with the wpautop filter.
* In order to reduce pageload on the rest of your site, the plugin only loads the Flot javascript on pages with the custom field 'flot' set to 'yes'.
