Hi,
You don't need to add it on my account... I just noticed it and
thought I would mention it. I should have just checked the source to
see it was not in there.

In this case I am more interested in building 3D representations of
ntuple data, rather than of symbolic variables.
That is, a 2D lego 'histogram' where the height of the x,y bin is set
by the value of z. A 3D graph, really.
Thanks,
Scott
