java.lang.Object
  echopoint.event.DefaultChartEventGenerator

All Implemented Interfaces:

ChartEventGenerator, java.io.Serializable

public class DefaultChartEventGenerator

extends java.lang.Object

implements ChartEventGenerator, java.io.Serializable

DefaultChartEventGenerator generates default action commands and tooltips for ChartEntity by calling the ChartEntity.getURLText() and ChartEntity.getToolTipText() respectively.

Remember you are not returning an URL in the traditional sense but rather a String that uniquely defines each peice of the chart. This string will be used as the action command of an ActionEvent
