Class GraphPanel

java.lang.Object
  java.awt.Component
      java.awt.Container
          javax.swing.JComponent
              com.moneydance.awt.graph.GraphPanel

All Implemented Interfaces:: java.util.EventListener, java.awt.image.ImageObserver, java.awt.MenuContainer, java.awt.event.MouseListener, java.awt.event.MouseMotionListener, java.io.Serializable

public abstract class GraphPanel
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
