3D surface plot..

[vacuumguy]

I have 10 probe which are measuring some fluxes on a circular wafer. So, I
have 3D data, x,y(position on a wafer) and z(flux). I want to make an in-situ
3D surface plot with these data with Labview. I couldn't find a way to do
that. Anyone knows how to do it?
Thanks

Look up the help pages on "intensity plots", which are probably more
appropriate and less CPU intensive. If you must plot it as a 3D surface,
look in the "Graph" controls palette and check out the "3D Surface Graph".
The help on these should be fairly easy to understand, given a knowledge of
arrays. If you do not understand arrays, read the relevant sections in the
manual- though to do anything in any language I think you quickly hit a need
for arrays..

If the data is in an ordered grid you can look at the sample VIs that ship
with LabVIEW. The sample VIs use the Plot3DSimpleSurface or Plot3DSurface
methods on the 3D graph (It is an ActiveX control).

However, if your data is not ordered you can use the Plot3DMesh method (use
the ActiveX invoke method) to create a surface. The Plot3DMesh method takes
three 1D vectors of data - X, Y, and Z (plus an optional fourth W vector) -
and triangulates a surface. The Plot3DMesh method is only available with
LabVIEW 6i or MeasurementStudio 3.0.1.

Attached is a VI that I wrote that demostrates the Plot3DMesh method on the
3D Graph. It's written in LabVIEW 6i.

Is there anyway to make legend to this graph? I have the same plot but I also want to see which color corresponds to which value.
