All Implemented Interfaces:

java.lang.Runnable

public class DrillThruPie

extends MappedImage

A pie-chart in which the elements are selectable so that the user can 'drill down' to further representations of the data. Lots and lots of paramaters all declared as public instance variables so that the creator can set them. If setting (any of) these you must set them before calling getMarkup().
