public class FunctionPlotter 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 FunctionCanvas 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 FunctionCanvas class.
