public class PMatrixRenderer
extends BackgroundRenderer

P-Matrix background renderer. The height is the Pareto density of the data evaluated at the neuron.

Field Summary

protected static org.apache.log4j.Logger	log interface to log4j system
protected ParetoDensity	pdens cache distance percentiles
protected int	percentile percentile parameter
protected double	radius radius parameter
protected boolean	useRadius flag whether to use radius instead of percentile

Constructor Summary

PMatrixRenderer()
Standard constructor

PMatrixRenderer(double radius)

Method Summary

ParetoDensity	getParetoDensity() Get the densitsy estimation used for the P-Matrix
int	getPercentile() Get the percentile parameter
double	getRadius() Get the radius parameter.
void	init() Optional initialization of background renderer.
void	init(Renderer renderer)
boolean	isColorBackground() Whether this background renderer returns color matrix.
cern.colt.matrix.DoubleMatrix2D	render(Renderer renderer) Calculate the height above each neuron with the P-Matrix method.
void	setPercentile(int percentile) Set the percentile parameter
void	setRadius() Set the radius parameter to the pareto radius

Constructor Detail

PMatrixRenderer

public PMatrixRenderer()

Standard constructor

PMatrixRenderer

public PMatrixRenderer(double radius)

Constructor with radius. Used to init radius from command line tools before data is available.

PMatrixRenderer

public PMatrixRenderer(int percentile)

Constructor with percentile. Used to init percentile from command line tools before data is available.

Method Detail

init

public void init(Renderer renderer)

render

public cern.colt.matrix.DoubleMatrix2D render(Renderer renderer)

Calculate the height above each neuron with the P-Matrix method.

Specified by:

render in class BackgroundRenderer

Parameters:

renderer - The invoking Renderer

isColorBackground

public boolean isColorBackground()

Description copied from class: BackgroundRenderer

Whether this background renderer returns color matrix. If false a height matrix is returned.

Specified by:

isColorBackground in class BackgroundRenderer

Returns:

true if this BackgroundRenderer returns colors, false if heights

getParetoDensity

public ParetoDensity getParetoDensity()

Get the densitsy estimation used for the P-Matrix

getPercentile

public int getPercentile()

Get the percentile parameter

setPercentile

public void setPercentile(int percentile)

Set the percentile parameter

Parameters:

percentile - The distance percentile to use for the radius.

getRadius

public double getRadius()

Get the radius parameter.

setRadius

public void setRadius(double radius)

Set the radius parameter.

Parameters:

radius - The radius to set.

setRadius

public void setRadius()

Set the radius parameter to the pareto radius

init

public void init()

Description copied from class: BackgroundRenderer

Optional initialization of background renderer.

Overrides:

init in class BackgroundRenderer
