All Implemented Interfaces:

Chart, RenderChangeListener, java.awt.event.MouseListener, java.awt.event.MouseMotionListener, java.awt.image.ImageObserver, java.awt.MenuContainer, java.awt.print.Printable, java.io.Serializable, java.util.EventListener, javax.accessibility.Accessible

public class BufferedChartPanel
extends AbstractChartPanel
implements RenderChangeListener

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.

Creates a new ChartPanel with the given model and title string.

Parameters:

model - the ChartDataModel

title - the title String

BufferedChartPanel

public BufferedChartPanel(ChartDataModel model,
                          java.lang.String title,
                          int coord)
