public class DensityPlot
extends javax.swing.JComponent

A component that displays a density plot (an overhead view of a matrix, with squares colored by value).

  Version 1.21, 4/30/07 - moved test case to examples/densityplot
  Version 1.2, 8/4/98 - added mask matrix option.
  Version 1.1, 7/8/98 - added orientation options, autoscaling options.
    doesn't copy matrix.
  Version 1.0, 7/2/98 - original version.

Constructor Detail

DensityPlot

public DensityPlot(DMatrix x,
                   ColorScale c)

A density plot needs a matrix and a color scale to draw it with.

Method Detail

getColorScale

public ColorScale getColorScale()

Return the color scale being used.

setColorScale

public void setColorScale(ColorScale x)

Set the color scale to use.

getMatrix

public DMatrix getMatrix()

Returns a copy of the matrix being drawn.

getMin

public double getMin()

Returns the minimum value currently being plotted.

getMax

public double getMax()

Returns the maximum value currently being plotted.

setMin

public void setMin(double x)

Set the minimum value to plot... turns off autoscaling of the minimum. When set to NaN, turns on autoscaling.

setMax

public void setMax(double x)

Set the maximum value to plot... turns off autoscaling of the maximum. When set to NaN, turns on autoscaling.

setMatrix
