Class PlotGrid

java.lang.Object
  org.generation5.util.Plot
      org.generation5.util.PlotGrid

All Implemented Interfaces:

Visualizable

public class PlotGrid

extends Plot

Plot data as a two-dimensional grid. Data can be passed as either a two-dimensional array of PlotPoints, or as a three-dimensional array of doubles. This class was primarily designed to facilitate the visualization of Kohonen neural network weights, but should work well in most other situations too.

Method Detail

setGridPoints

public void setGridPoints(PlotPoint[][] gridPoints)

Set the grid points as a two-dimensional array of PlotPoints. Note that this will set any data set with setGridPoints(double[][][]) to null.

Parameters:

gridPoints - a two-dimensional array of PlotPoints.

setGridPoints

public void setGridPoints(double[][][] gridPoints)

Set the grid points as a three-dimensional array of doubles. Note that this will set any data set with setGridPoints(PlotPoint[][]) to null.

Parameters:

gridPoints - the grid points.

render

public void render(java.awt.Graphics g,
                   int width,
                   int height)

Render the grid on a graphics context.

Specified by:

render in interface Visualizable

Specified by:

render in class Plot

Parameters:

g - the graphics context.

width - the width of the context.

height - the height of the context.
