Hi, Thanks very, very much for your answer.
> Would plgriddata do what you need? > http://plplot.sourceforge.net/docbook-manual/plplot-html-5.9.0/plgriddata.html Yes, I think thats exactly what I want. The "Delaunay Triangulation Linear Interpolation" method should do a fine job for my case. But I'll try the cubic spline method, too. > plshades (or multiple calls to plshade) can generate the actual plot. > http://plplot.sourceforge.net/docbook-manual/plplot-html-5.9.0/plshades.html Thank you. I'll have a closer look at plshade this weekend to understand what this is really doing. > PLplot does not have a built-in function to draw a color bar.

Great. Looks like what I want. I'll try it and report. Thank you very much.
