public class PlotPanel

extends javax.swing.JPanel

implements java.beans.PropertyChangeListener

This class implements a panel that display the distributions of the selected exemplars. The distributions are derived by summing the small Gaussian on each instance within the exemplar. Details see Detterich et al's MI paper.

Method Detail

propertyChange

public void propertyChange(java.beans.PropertyChangeEvent pce)

The handler function when property changes are informed. there are lots of properties can be listened by this class: the exemplars to be plotted, the colors from the ClassPanel, x axis value and index, and std. dev. Only all these parameters are set can the distribution be plotted

Specified by:

propertyChange in interface java.beans.PropertyChangeListener

Parameters:

pce - the property change event

setStdDev

public void setStdDev(double sd)

setColours

public void setColours(weka.core.FastVector cols)

Set a list of colours to use when colouring points according to class values or cluster numbers

Parameters:

cols - the list of colours to use

setMaxC

public void setMaxC(double maxc)

setMinC

public void setMinC(double minc)

setXValue

public void setXValue(Axis anx)

Set the index of the attribute to go on the x axis

getXValue

public Axis getXValue()

Return the current max value of the attribute plotted on the x axis

Returns:

the x value

getMaxY

public double getMaxY()

Return the current max value of the attribute plotted on the y axis, i.e. 1/[sqrt(2*PI) * std. dev.]

Returns:

the max y value

setPlotExemplars

public void setPlotExemplars(Exemplars added)
                      throws java.lang.Exception

Sets the exemplars to be plotted

Parameters:

added - the exemplars

Throws:

exception - Exception if exemplars could not be set

java.lang.Exception

convertToAttribX

public double convertToAttribX(double scx)

convert a Panel x coordinate to a raw x value.

Parameters:

scx - The Panel x coordinate

Returns:

A raw x value.

convertToAttribY

public double convertToAttribY(double scy)

convert a Panel y coordinate to a raw y value.

Parameters:

scy - The Panel y coordinate

A raw y value.

convertToPanelX

public double convertToPanelX(double xval)

Convert an raw x value to Panel x coordinate.

Parameters:

xval - the raw x value

Returns:

an x value for plotting in the panel.

convertToPanelY
