Grid example

Hi all,
another problem.... Imagine that a want to plot a table N x N with
different colors using a colored grid. To obtain the right SGT data
object I used the Grid example and I wrote

     Range2D xr = new Range2D(0.0f, 6.0f, 1.0f);
     Range2D yr = new Range2D(0.0f, 6.0f, 1.0f);

     double[] x = {1,2,3,4,5,6};
     double[] y = {2,5,6,2,1,3};
     double[] z = {10,20,30,40,50,29};

     SimpleGrid sg = new SimpleGrid(z,x,y,"TEST");
     newData = sg.copy();

     /*
      * Create a ColorMap and change the style to RASTER_CONTOUR.
      */
     ColorMap cmap = createColorMap(datar);
     gridAttr_.setColorMap(cmap);
     gridAttr_.setStyle(GridAttribute.RASTER_CONTOUR);
     /*
      * Add the grid to the layout and give a label for
      * the ColorKey.
      */
     rpl.addData(newData, gridAttr_, "");

I obtain an error like newData unknown source at this last line

The problem is that I do not understand what is now the function used in
the grid example:

 ColorMap createColorMap(Range2D datar) {
    int[] red =   { ...};
    int[] green =  { ...};
    int[] blue =  { ...};
    IndexedColorMap cmap = new IndexedColorMap(red, green, blue);
    cmap.setTransform(new LinearTransform(0.0, (double)red.length,
       datar.start, datar.end));
    return cmap;
  }

Could someone tell me more about this?
:)))
Thanks a lot
