public class ClassPanel

extends javax.swing.JPanel

This panel displays coloured labels for nominal attributes and a spectrum for numeric attributes. It can also be told to colour on the basis of an array of doubles (this can be useful for displaying coloured labels that correspond to a clusterers predictions).
