Move the values in an array.
By use of MSChart control you can draw chart for the values in an array.
The below link shows how to plot 2d Bar chart for the given array values.

You change the chart type property to 3D for your problem.
I dont want to use the MSchart tool. i want to code it for all rotations, position movement using trignometry functions.

Do you want to make a perspective projection of graphs, using trigonometry and VB drawing functions?
It is not a simple task. You can imagine your graphs as 3D objects, and you have to make projection of x,y,z coordinates to a drawing x,y surface.
Trignonometry functions for 3D projecton could be found somewhere on internet, I have seen it (not tried) but unfortunatelly I have no link saved.
Another problem is rendering, but it can be easily solved. You have to sort items (depending on viewing angle) to first draw hidden items.
