Thanks for the information. But how can I set the option in a C++ program which is linked with the
root library?
For example:
Canvas1 = new TCanvas("Vertex Fitting", "Vertex Fitting",200,10,700,840);
Pad1 = new TPad("MainPad1","The first Pad " ,0. ,0.40,0.50 ,0.80 ,CanvasColor);
Pad1->cd();
sampleHist->Draw();

I could not find any inheritance of TStyle in TCanvas or TPad or TH1F...
