Due to the current gap in continued funding from the U.S. National Science Foundation (NSF), the NSF Unidata Program Center has temporarily paused most operations. See NSF Unidata Pause in Most Operations for details.
Hi John, > I'm just starting out with VisAD and have been successful creating a > variety of 3D surface plots.

TIA The general pattern for a scatter plot is data in a FlatField with MathType (index -> (a, b, c, ..., z)) and ScalarMaps: a -> XAxis b -> YAxis c -> ZAxis where any range RealTypes (i.e., any letters a - z) can be substituted for a, b and c in these ScalarMaps. You can add other ScalarMaps to color components (e.g., Red, Green, Blue, RGB) and to SelectRange. The domain of your field doesn't have to be a 1-D 'index', but may be a 2-D image domain such as (line, element). The key idea in a scatter diagram is that domain RealTypes are not mapped to spatial display axes, but that range RealTypes are. Cheers, Bill
