Hi Jochen,
Did you miss my reply to your similar question to roottalk
on September 12? see my answer at:
http://root.cern.ch/root/roottalk/roottalk02/3856.html
Concerning your question about the TLegend font: You can
do the following:
TLegend *leg = new TLegend(0.6,0.7,0.85,0.8);
TLegendEntry *le1 = leg->AddEntry(h,"A Gaussian distribution");
le1->SetTextFont(72);
The text font cannot be set currently via the TStyle. I will add an option
to do it.
