3. Transparent Bars

Hi all, I am drawing a overlaid bar graph and I want the bars in the bargraph at the top to be transparent,so that i can visualize the bars at the bottom.I think this problem can be solved if we can make the bars of a simple bargraph transparent.I am not getting much of a clue.Please help. Regards, Abhishek.
