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?
