I can solve this plot with Matlab or Mathematica resulting a figure like the attached file CH.png

but I do not know how to plot this figure with Gnuplot. If a solution is possible I also would like to add transparency to the planes that form the hull.

Thank you very much for the forum help]]>

You can use the "splot" command to do this, but it will require

you to munge your data first. The "splot" command will draw

a surface over a base plane. If you present your coordinates

as such (once for the "top" and "sides" of your body, and once

for the "bottom"), then "splot" should do what you are asking

for.

Be aware that "splot" will not find the convex hull of a set of

coords, though. You will have to prepare your data to indicate

what constitutes the faces of the body in question. Check the

reference documentation (or my book) for the required data

format.
