3D Plot [message #23713]

Hey all,

I have been trying to create a 3D plot. I have a two dimensional array
that holds the z values. I just want to plot a point at that point in 3D
space, so if I have data(1,2) = 3 then i want to put a point at x = 1, y
=2 and z = 3. However, with the surface command a line is always drawn to
connect this point with other points. Is there another command I am not
familiar with or any other ideas?

Thanks

Mike

I think maybe you are looking for a 3D scatter plot:
