Hi
I have two datasets, one is 350x700 another is 900x1500.
I use the alomost same VisAD code to display them in Lat-Lon 2D domain,
except the length of data samples is different,
display = new DisplayImplJ3D("display", new
TwoDDisplayRendererJ3D());
latMap = new ScalarMap(RealType.Latitude, Display.YAxis);
lonMap = new ScalarMap(RealType.Longitude, Display.XAxis);
display.addMap(latMap);
display.addMap(lonMap);
imageValue = RealType.getRealType("image");
rgbMap = new ScalarMap(imageValue, Display.RGB);
display.addMap(rgbMap);
imageRef = new DataReferenceImpl("image");
display.addReference(imageRef);
.........
I could get a color display for dataset with less data samples but a
grey display for the large dataset.
The interest thing is:
when I click on the display (since PointManipulationRendererJ3D has
been added to the above display), I could get the correct lat, lon and
data value at the point I have clicked.
Does anyone know why I end up with a grey display for the larger
dataset?
By the way, I am on SGI IRIX with

Thanks for your great help.
