Hi,

What do you mean by associatedData?

I use it with double arrays with following constraints: grid.length ==
xloc.length*yloc.length

then, if sg is the new SimpleGrid.
    sg.setXMetaData(new SGTMetaData("Distance","km"));
    sg.setYMetaData(new SGTMetaData("Height","m"));
    sg.setZMetaData(new SGTMetaData("Depth","cm"));

then put it in a JPlotLayout

    /*
     * Create the layout without a Logo image and with the
     * ColorKey on a separate Pane object.
     */
    JPlotLayout rpl = new JPlotLayout(true, false, false, "test layout",
null, true);
    rpl.setEditClasses(false);
    /*
     * Create a GridAttribute for CONTOUR style.
     */
    Range2D datar = new Range2D(-20.0f, 45.0f, 5.0f);
    //Range2D datar = new Range2D(0.0f, 1.0f, 5.0f);
    clevels = ContourLevels.getDefault(datar);
    gridAttr_ = new GridAttribute(clevels);
    /*
     * 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_, "Test data");

    rpl.setTitles("Demo d'essai",
                  "Utilisant JPlotLayout",
                  "et voila =)","");

    rpl.setSize(new Dimension(500, 400));
    rpl.setKeyLayerSizeP(new Dimension2D(2.0, 6.0));
    rpl.setKeyBoundsP(new Rectangle2D.Double(0.01, 5.99, 1.98, 5.98));

Help!

I'm a new user, trying to use SGT for a simple applet
demo, and cannot seem to create a valid SimpleGrid for
passing into a JGridDemo setup...  (I have started
with your JGridDemo.java example, and am trying
to replace the TestData with my own data grid).

I have created a SimpleGrid using the

( double [] grid, double [] xloc, double [] yloc, String )

constructor, with X and Y coordinates in xloc[] and yloc[],
resp, and Z values in grid[], but the resulting SimpleGrid
has null "AssociatedData"...?!

How do I get my "Z" values (the actual data) into the grid?

Any help would be greatly appreciated, ASAP!

Thanks Much!
