RE: build doman_set ?

Dear all:
 i have similar problem to yours with the full description below:
below are sample lines in my file:

private static final int NUM_SPIKES_X = 4; 

  // number of spikes along Y axis 
  private static final int NUM_SPIKES_Y = 3; 
// increase density value to make spikes "thinner" 
  // decrease density value to make spikes "thicker" 
 private static final int DENSITY = 8; 

and then i construct the integer2Dset with the density and spikes_Y and X
using the constructor 

 Integer2DSet set = new Integer2DSet( 

then i have the two for-loops to read the spike value and put on the grid.i
think that is causing the scale mis-match,each oject carrying the spike
value also carries a pi value and a mass value.but this values are not
mapped to the x and Y axis as it is supposed to.

String name=(String)pro.getName(); 
            double ratiox=pro.getProp(); 
            double massx=pro.getMass(); 
            double pix = pro.getPi(); 
so the domain gat to be numbers like massx and pix values taken from the
prodat oject instead of the DENSITY * NUM_SPIKES_X, DENSITY * NUM_SPIKES_Y

so it is clear that, if there is a way to pass the mass value and the pi
value through the integer2Dset constructor so that each spike will
correspond to a mass value and a pi value in the it stands now,
the domain is independent and NOT connected to the range logically.The data
is not fully represented very i am looking for ways to include the
mass and pi values in the domain on the grid so that the scale for the pi
and mass will match can test it using the sample below:

sample data below:

BC10_HUMAN      902869  6.21    .10714285714285712 

Everything about  the display is fine except this issue of domain and scale.

it will be good to know some workarounds on this or any constructor that can
implement this. 

thanks for all your time

If your points are arranged in a curved 2-D grid, then use
the Gridded2DSet constructor:

  public Gridded2DSet(MathType type, float[][] coord, int lengthX, int

whree lengthX * lengthY = 1000.

Otherwise use the Irregular2DSet constructor:

   public Irregular2DSet(MathType type, float[][] coord)

Good luck,
