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.
