More than one graph in a Canvas

ROOT

Greetings root users,

Could any one kindly help me and say how I can have different graphs in a single Canvas, in order to be able to compare them and label them?

Thnak you in advance

Create a TCanvas and divide it into Pads using the TCanvas::Divide() method, for instance if plot1 and plot2 are two TGraph graphics and histo is a TH1 histogram write:

TCanvas *cvs = new TCanvas("cvs","A title...");
cvs->Divide(2,2);
cvs->cd(1);
.....
.....   // options
plot1->Draw();

cvs->cd(2);
.....
.....
plot2->Draw();

cvs->cd(3);
.....
.....
histo->Draw();

Hej Again,

I felt I’d better attach my files for a better reference. each file contain three histograms. but I want to compare all the number 2s for example.

Many thanks again

What did you try? How did it fail?

Philippe,

I think you can ignore this post. I have already answered this question (and many more !) here:
