implements java.awt.event.ActionListener

A ScatterPlotApplet shows a scatter plot of data from a DataTableInput. The user can enter the data in a two-column table that is shown in the applet. It is also possible to configure the applet with a menu of file names. These files, which must be in the same directory as the Web page on which the applet appears, will appear in a menu. A file can contain data for the table, with two numbers per line. When the user loads the file, the data replaces the data in the table.

Constructor Detail

ScatterPlotApplet

public ScatterPlotApplet()
Method Detail

init

public void init()
The init() method is called by the system to set up the applet. If the applet does not appear as a button, then init() creates the main panel of the applet and calls setUpMainPanel to set it up.

Overrides:
init in class java.applet.Applet

makeMainPanel

public javax.swing.JPanel makeMainPanel()
Create the main panel of the applet.

Returns:
the newly made panel

actionPerformed

public void actionPerformed(java.awt.event.ActionEvent evt)
Respond when user clicks a button; not meant to be called directly. This opens and closes the separate window.

Specified by:
actionPerformed in interface java.awt.event.ActionListener
Parameters:
evt - the event created when the user clicked the button

getParameter

protected java.lang.String getParameter(java.lang.String paramName,
                                        java.lang.String defaultValue)
Return the applet parameter with a given param name, but if no such applet param exists, return a default value instead.

Parameters:
paramName - the name of the parameter
defaultValue - the value to return if not set
Returns:
the parameter's value
