All Implemented Interfaces:

public class ChartPanel
extends AbstractChartPanel

This Panel provides the possibility to include a Chart into a Swing Application. I choose not to make every Chart extend JComponent because of the overhead this would have meant. Instead, this class is an adaptor. It implements the Chart interface and contains a DefaultChart instance to which all Chart calls are promoted.
