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...
