When I do this:
TH1F * hist = new TH1F("hist","hist",7,-0.5,6.5); TCanvas * c1 = new TCanvas; c1->SetFillColor(0); gStyle->SetOptStat(0); hist->SetTitle(""); hist->Draw();
there is a a red tint on the x axis and the right vertical axis. I attached a picture. Does anyone know how to get rid of this red tint?
