I'm sure I'm doing this the long way around: I have sea surface temperature data to plot overlaid on a rubbersheeted bathymetry surface model (along with other data eventually). It all works perfectly (a nice flat, transparent layer at altitude zero over the nicely colored bathy data), but...
The data has X (longitude), Y (latitude), Z (0 for sea level) and temperature in deg C. I have imported the four column dataset OK as 3D with one data column, the layer plots (just as I want) at sea level, but I can't work out how to color it by the temperature column (DX colors by the Z value, so I get a constant color). The kludge that I got working is to generate 2 xyz files, the first has 0 (zero) as the Z, the second file has X, Y, temperature. The second dataset is draped over the first to do just what I want. I figure DX can do it with the single 4 column input, I'm just too obtuse to work out how :-) Can someone please toss a pointer my way? (I'll have a few more queries as I work towards my goal :-) Thanks, Brent Wood __________________________________________________ Do You Yahoo!? Great stuff seeking new owners in Yahoo!
