Setting a Z-axis projection on TH2D Histogram

ROOT
1

Hi
I don’t know asking this question is right or not. I have declared a TH2D histogram. After executing the macro I can see the histogram in 2 dimensions only. Is there any way so that I can project the graph on the Z-axis and it displays like 3d surface.
Thank you
