Hi Sadik,

Thanks for your reply. But I am looking to plot markers on X-Y plane and not in 3D. Because, I have a 2-D plot where the colormap is representing the third dimension.

Say, the third dimension is Z-value....

What I am trying is to plot markers on the colormap for some specific values of Z. I am not plotting Z here, but plotting markers with XY location denoted by V1() and V2().

I hope it's clear to you now. Thanks,
