I am trying to use PV-Wave to display a discrete data of x,y,z form. Because it is discrete neither surface nor shade_surf are appropriate but I can find no way to easily produce a 3d histogram and would like to avoid writing the code to produce one if it has already been done. Is a PV-WAVE program available to produce 3d shaded histograms from ftp?

Look at it; maybe you can need it or at least get the idea how to solve your problem.

I don't know about PV-Wave, but in IDL there is a users-library function called LEGO. It's pretty old (1991), so it may also be available in PV-Wave.
