From: Alexm Smith on 10 Mar 2010 19:15 I have x,y,z data, each in a column, but I've tried different ways to get the 3D plot, z vs. x and y plane, of coz. Since I don't know the explicit function form of z concerning x and y. How can I do this? I want the 3D surface, not scattered points or curve. Thank you so much!
