Draw Graph on OnGUI

I need to draw graphs on GUI.
Has anyone ever done this?

I thought a work around would be to have a hole in my gui and put a plane behind it and use Vectrocity to draw my graphs in front of the 3D plane.
Awesome … but … different browsers render the world differently and there is the zoom issue in the browser. Gui is screen coords and the Plane behind is in world coords.
Between the two I cant get the plane to align consistently behind the gui.

So, I give. Has anyone out there drawn graphs on a gui object?
If so, how the heck did you do it?
Thanks …

So it would appear that there is no solution to this problem.
My work around is to create movies of the graph being drawn using my gui with a hole in
it.
Then exporting bitmaps from that.
Storing them in sub dirs under Resources.
Then playing those bitmaps using GUI.DrawTexture
The result is pretty convincing, solves the immediate problem and gets the objective
covered … but " … it just aint right … "
The big down side is that obviously this is not dynamic graphing.
But more importantly it has jacked up the app overhead tremendously.

I dearly hope the GUI in V5 proves to be a game changer and not more of the same …
