All Implemented Interfaces:

DataTableListener, Plotter, java.awt.image.ImageObserver, java.awt.MenuContainer, java.io.Serializable, javax.accessibility.Accessible

public class DensityPlotter
extends PlotterAdapter

The density plotter does not only plot the single plot points but also tries to calculate a color for all pixels in between.

Constructor Detail

DensityPlotter

public DensityPlotter()

DensityPlotter

public DensityPlotter(DataTable dataTable)

Method Detail

setDataTable

public void setDataTable(DataTable dataTable)

Description copied from class: PlotterAdapter

Since this method already adds this object as a listener, all methods overriding this one should invoke the super method.

Specified by:

setDataTable in interface Plotter

Overrides:

setDataTable in class PlotterAdapter

getNumberOfAxes

public int getNumberOfAxes()

Description copied from class: PlotterAdapter

Returns 0. Subclasses overriding this method should also override PlotterAdapter.getAxisName(int), PlotterAdapter.setAxis(int, int), and PlotterAdapter.getAxis(int).

Specified by:

getNumberOfAxes in interface Plotter

Overrides:

getNumberOfAxes in class PlotterAdapter

getAxis

public int getAxis(int axis)

Description copied from class: PlotterAdapter

Returns -1. Subclasses overriding this method should also override PlotterAdapter.getAxisName(int), PlotterAdapter.setAxis(int, int), and PlotterAdapter.getNumberOfAxes().

Specified by:

getAxis in interface Plotter

Overrides:

getAxis in class PlotterAdapter

getAxisName

public java.lang.String getAxisName(int index)

Description copied from class: PlotterAdapter

Returns null. Subclasses overriding this method should also override PlotterAdapter.getAxis(int), PlotterAdapter.setAxis(int, int), and PlotterAdapter.getNumberOfAxes().

Specified by:

getAxisName in interface Plotter

Overrides:

getAxisName in class PlotterAdapter

setAxis

public void setAxis(int index,
                    int dimension)

Description copied from class: PlotterAdapter

Does nothing. Subclasses overriding this method should also override PlotterAdapter.getAxis(int), PlotterAdapter.getAxisName(int), and PlotterAdapter.getNumberOfAxes().

Specified by:

setAxis in interface Plotter

Overrides:

setAxis in class PlotterAdapter

getPlotName

public java.lang.String getPlotName()

Description copied from class: PlotterAdapter

Returns null. Subclasses might return another name more fitting the plot selection box or list.

Specified by:

getPlotName in interface Plotter

Overrides:

getPlotName in class PlotterAdapter

setPlotColumn

public void setPlotColumn(int index,
                          boolean plot)

Description copied from class: PlotterAdapter

Does nothing. Subclasses should override this method if they want to allow plot column selection. In this case, the method PlotterAdapter.getPlotColumn(int) should also be overriden.

Specified by:

setPlotColumn in interface Plotter

Overrides:

setPlotColumn in class PlotterAdapter

getPlotColumn

public boolean getPlotColumn(int index)

Description copied from class: PlotterAdapter

Returns false. Subclasses should override this method and return true for the columns which should be plotted.

Specified by:

getPlotColumn in interface Plotter

Overrides:

getPlotColumn in class PlotterAdapter

prepareData

private void prepareData()

changeColor

private void changeColor(double[][] colorMatrix,
                         int matrixX,

                         int radius)

paintComponent

public void paintComponent(java.awt.Graphics graphics)

Description copied from class: PlotterAdapter

Invokes super method and sets correct color schemes. Should be overwritten by children, but invokation of this super method must still be performed in order to get correct color schemes.

Overrides:

paintComponent in class PlotterAdapter

paintDensity

private void paintDensity(java.awt.Graphics2D g,
                          int pixWidth,

                         int pixHeight)

isProvidingCoordinates

public boolean isProvidingCoordinates()

Description copied from class: PlotterAdapter

Returns false. Subclasses might override this method in order to indicate that this plotter is able to deliver plot coordinates. Please note that overriding subclasses should also override PlotterAdapter.getPositionInDataSpace(Point).
