Flotr2 Pie Chart

We are using the Flotr2 library to make a pie chart here.

To add a pie chart to your exhibit, you must include the flotr extension for Exhibit (in addition to the Exhibit API):

 <link rel="exhibit-extension" href="http://projects.csail.mit.edu/exhibit/api/extensions/flotr/flotr-extension.js"/>

To include a pie chart, add to your HTML

 <data-ex-role="view" 
            data-ex-view-class="PieChart" 
            data-ex-values=".cases"
            data-ex-labels=".country">
         </div>

Replace .cases and .country with appropriate expressions.

Other settings include:

setting name	type of value	default	choices	meaning
plotHeight	int	400		Height of the plot in pixels
plotWidth	int	700		Width of the plot in pixels
explode	int	6		Separation between the slices
group	boolean	false	true, false	All items less than the cutoff will be grouped into one slice
cutoff	float	0.01		Cutoff used to group items into one slice
