public class ScatterPlotApplet extends java.applet.Applet 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.- See Also:

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 classjava.applet.Applet
-
makeMainPanel
public java.awt.Panel makeMainPanel()
-
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 interfacejava.awt.event.ActionListener
-
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.
