Yes, I kind of thought about that myself... Thanks! I will just drop it. Mihai Nica, ABD Jackson State University 170 East Griffith Street G5 Jackson, MS 39201 601 914 0361

You may want to try persp, or wireframe in lattice.
That was what I thought first, but I think it actually is the 3D histogram or exploding pie chart question, how to make a 3D representation of columns of regular or irregular polygons scaled by some z variable in height. The reader will see different things depending on viewing point and height, I would not in general recommend it as either a presentation or analytic graphic. Roger
