Method Detail

getVisualizeMenuItem

public JMenuItem getVisualizeMenuItem(weka.core.Instances predInst)

Get a JMenu or JMenuItem which contain action listeners that perform the visualization of the classifier errors.

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.
