Class EntropyTrianglePlugin

java.lang.Object

weka.gui.visualize.plugins.EntropyTrianglePlugin

All Implemented Interfaces:

TechnicalInformationHandler, MainMenuExtension, ErrorVisualizePlugin

public class EntropyTrianglePlugin
extends Object
implements ErrorVisualizePlugin, MainMenuExtension, TechnicalInformationHandler

This class acts as a launcher for the Entropy Triangle Plugin from the visualization plugin context menu of the Weka explorer and from the Extensions menu in the Weka GUI Chooser window.

The same window, and EntropyTrianglePanel, is shared for both invoking sources. This way can be added instances from the explorer to a plot of a instances loaded from a file.

The panel data is cleared when the user closes the window.

Method Detail

getVisualizeMenuItem

public JMenuItem getVisualizeMenuItem(Instances predInst)

Get a JMenu or JMenuItem which contain action listeners that perform the visualization of the Entropy Triangle.

The actual class is the attribute declared as class attribute, the predicted class values is found in the attribute prior to the class attribute's position. In other words, if the classIndex() method returns 10, then the attribute position for the predicted class values is 9.

Exceptions thrown because of changes in Weka since compilation need to be caught by the implementer.

Specified by:

getVisualizeMenuItem in interface ErrorVisualizePlugin

Parameters:

predInst - the instances with the actual and predicted class values

Returns:

the menu item for opening the visualization or add the data if the Entropy Triangle already exists.
