Dear Rooters!

While trying to draw a histogram stored in a ROOT file:

TH2D* histo = (TH2D*) file->Get("histo");
histo->DrawCopy("colz");

the option "colz" was completely ignored and the scatter plot was drawn. I
cannot even modify the option using the DrawPanel or with
TH2D::SetOption().

Is this a problem with TH2D or a scoping problem?

Cheers,
	Ulrich
