com.singularsys.jepexamples.applets.PolarPlotter

All Implemented Interfaces:

java.awt.image.ImageObserver, java.awt.MenuContainer, java.io.Serializable, java.util.EventListener, javax.accessibility.Accessible, javax.swing.event.ListSelectionListener, javax.swing.RootPaneContainer

public class PolarPlotter
extends javax.swing.JApplet
implements javax.swing.event.ListSelectionListener

This applet is a demonstration of the possible applications of the Jep mathematical expression parser.

The FunctionPlotter class arranges the text field and GraphCanvas classes and requests a repainting of the graph when the expression in the text field changes. All plotting (and interaction with the Jep API) is performed in GraphCanvas class.
