public class MatrixPanel
extends javax.swing.JPanel

This panel displays a plot matrix of the user selected attributes of a given data set. The datapoints are coloured using a discrete colouring set if the user has selected a nominal attribute for colouring. If the user has selected a numeric attribute then the datapoints are coloured using a colour spectrum ranging from blue to red (low values to high). Datapoints missing a class value are displayed in black.
