Wind Rose

Documentation
This demo illustrates a wind rose using the PolarChart widget. To specify chart arguments that correspond to cardinal points, the discreteAxisDivisionMode and firstPointOnStartAngle options of the argumentAxis object are set. In addition, the chart’s onLegendClick event is handled for you to be able to exclude/include certain series to the PolarChart at runtime.
