All Implemented Interfaces:

java.util.EventListener, java.awt.image.ImageObserver, java.awt.MenuContainer, java.awt.event.MouseListener, java.awt.event.MouseMotionListener, java.io.Serializable

Direct Known Subclasses:

JBarGraph, JLineGraph, JPieGraph

public abstract class JGraph

extends javax.swing.JComponent

implements java.awt.event.MouseMotionListener, java.awt.event.MouseListener

Description: This is an abstract class that implements the common functionality required for all types of graphs. Specific graph types such as Bar, Line, or Pie, should subclass this class
