st: 3D bar plot

Dear listers
What is the command for drawing a 3D bar plot? by 3D bar plot it is meant -
Suppose our data set is {(x,y,z)}={(8.3, 2.3, 2), (9.2, 1.8, 4), (7.1, 0.9, 5)}
For each point in the (x,y) plate, a vertical bar with height that equals the corresponding z value is drawn. ie., in the position (x,y)=(8.3,2.3), a vertical bar of length 2 is presented, ....
When x and y represent, respectively, within-person mean and within-person standard deviation, and z the frequency of the corresponding pattern, this plot should give a graphic summary of the panel data.
Or, what is a good way to describe panel data? We need something similar to freq, but able to look after two aspects here.
Thanks very much for any suggestions.
Ning
