How can I overlay bar3 plot on an image?

Hi there, I got a problem with bar3 plot.

I have a geographical map image on which I want to overlay a 3D bar which indicate some magnitude/abundance data at certain coordinates. I have managed to stack them together using hold on command in MATLAB, but this is what I get.

Questions: 1. how to make the base of the bar graph invisible so what appear is only the 3D Bar? 2. how to make the bar graph erected in a certain predetermined coordinate?

Any help will be appreciated.
