I am making slow but sure progress, thanks to this list. NOW: I made the 3D graph and got a screen capture of it. Question: why is my 3D now giving me a rectangular sheet? It does not show the corner square in the Fast 3D graph (so my graphs looks almost like a triangle at the bottom. When I go to Wireframe it seems I get the "sheet" look from the graph. I am attached a screen shot here. Also: why can't I rotate a Wireframe graph?
thank you
John
