Class FunctionPlotter

  • 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
    Direct Known Subclasses:
    FieldFunctionPlotter
    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.
