    • setUpBottomPanel

      protected void setUpBottomPanel()
      Description copied from class: GenericGraphApplet
      This method checks the applet parameter "UseFunctionInput". If the value is anything but "no", then a panel is created that contains an ExpressionInput (stored in the member variable functionInput) and possibly a ComputeButton and lable for the input box. This panel is a JCMPanel using BorderLayout. In is stored in the member variable inputPanel and is added to the SOUTH position of the mainPanel. The method also processes applet parameters "Function", "UseComputeButton", "ComputeButtonName", and "FunctionLabel". The ComputeButton, if it exists, is stored in the member variable computeButton. Note that nothing at all is done by this method if the value of the applet parameter "UseFunctionInput" is no.

    • setUpCanvas

      protected void setUpCanvas()
      Description copied from class: GenericGraphApplet
      This method is called by mainPanel() to set up the display canvas and add it to the main panel. The canvas already exists in the member variable canvas when this method is called. This method adds only a set of axes to the canvas, sets the mainController to report errors using the canvas, and adds the canvas to the CENTER of the main panel. This method processes applet parameters "UsePanner", "CanvasColor", "UseMouseZoom", and "UseOffscreenCanvas". Typically, this method will be overridden in subclasses to add more Drawable items to the canvas. In this case, super.setUpCanvas() should be called first.

    • doLoadExample

      protected void doLoadExample(String example)
      Description copied from class: GenericGraphApplet
      This method is called when the user loads an example from the example menu (if any). The parameter is the string that defines the example. By default, this method does nothhing. It should be overridden to load the example.
