public class MatrixPanel
extends 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.

setPlotSize

public void setPlotSize(int plotSize)

Set the plot size

Parameters:

plotSize - the plot size to use

setPlotBackgroundColour

public void setPlotBackgroundColour(Color c)

Set the background colour for the cells in the matrix

Parameters:

c - the background colour

applySettings

public void applySettings(Settings settings,
 String ownerID)

Parameters:

settings -

ownerID -

updatePanel

public void updatePanel()

Update the display. Typically called after changing plot size, point size etc.
