public class ERPPieChart
extends ERPChart

Displays a Pie chart with an optional map. The most important binding is items which should contain an array of objects from which the values nameKey and valueKey are retrieved. For example, you might have an array of line items, with a valueKey amount and a nameKey product.name. If you supply a PieDataset instead, this will get used instead of the other bindings.

Bindings

name	the name of the chart
chartType	the type of the chart (possible values depend on the concrete subclass)
imageType	the type of the image to show: png (default) or jpeg
width	the width of the chart (400 pixel if not specified)
height	the height of the chart (400 pixel if not specified)
dataset	Dataset to use. If this is given, then items, nameKey, valueKey and categoryKey are not considered.
items	array of values to display the chart for
nameKey	the key for the name (must return String)
valueKey	the key for the value (must return Number)
showLegends	true, if legends should be shown
showLabels	true, if labels should be shown (default is true)
showToolTips	true, if tool tips should be shown
showUrls	true, if urls should be shown
chart	Chart to use instead of the created one. If this binding is setable, then it will be set to the actually used chart
configuration	NSDictionary that will be applied to the chart via key-value-coding prior to rendering. Contains entries like antiAlias=true or categoryPlot.dataAreaRatio = 0.8.
