All Implemented Interfaces:

com.tonbeller.wcf.bookmarks.Bookmarkable, com.tonbeller.wcf.component.Component, java.util.EventListener, com.tonbeller.wcf.component.Form, com.tonbeller.wcf.component.FormListener, javax.servlet.http.HttpSessionBindingListener, com.tonbeller.wcf.component.LifeCycle, com.tonbeller.jpivot.core.ModelChangeListener, com.tonbeller.wcf.component.Renderable, com.tonbeller.wcf.controller.RequestListener, com.tonbeller.wcf.component.RoleExprHolder, com.tonbeller.wcf.component.Visible

public class EnhancedChartComponent

extends com.tonbeller.jpivot.chart.ChartComponent

implements com.tonbeller.jpivot.core.ModelChangeListener

Started as an exact copy of com.tonbeller.jpivot.chart.ChartComponent. Needed to enhance the render functionality to handle different series colors and palettes. There was no way to overload, override that functionality without copying a significant amount of the class, so here is a complete copy. Will likely evolve into something quite different.
