Dear Rooters, I would like to change some parameters of the global styles, e.g. changing the font to Roman on histogram labels, axis, legends etc. I know how to this for each object (h->GetXaxis()->SetTitleFont(22)), but I want to do this once at the beginning of a macro and not separately for each object. Therefore I created a style like in the attached macro. But I encounter several problems: - the font for the Yaxis is not changed - how to change the font for the legend in the style definition? - as described in the manual, the new style must be called before reading objects from a file. Then how can I make in one macro two plots from the same histogram (read from a file), first with MyStyle1 and then with MyStyle2? The obvious way would be something like this (assume there is a canvas divided into two pads): c1_1->cd() gROOT->SetStyle(MyStyle1); hist->Draw(); c1_2->cd(); gROOT->SetStyle(MyStyle2); hist->Draw(); But as I understand from the manual this won't work. I am using the HEAD version of root on RedHat7.2.1. Thanks, Jochen { gROOT->Reset(); TStyle *Sty = new TStyle("MyStyle","My Style"); Sty->SetTitleFont(22); Sty->SetLabelFont(22); Sty->SetOptStat(0); gROOT->SetStyle("MyStyle"); TH1F *h = new TH1F("h","A Gaussian distribution",20,-3,3); h->FillRandom("gaus",1000); h->GetXaxis()->SetTitle("X-Title"); h->GetYaxis()->SetTitle("Y-Title"); h->Draw(); TLegend *leg = new TLegend(0.6,0.7,0.85,0.8); leg->AddEntry(h,"A Gaussian distribution"); leg->Draw(); }
