Hello, I have multiple plots. I want to save them with a name along with a number in increasing order using a loop. Something like: file1.pdf file2.pdf ... Can anyone suggest how can I do this? There are many plots which makes manually saving each of them very tedious. Is there a quick way t…

Double_t min, max; TH1F *myhist[npeaksFound]; char *histname = new char[npeaksFound]; TCanvas *ch=new TCanvas(histname,"ch"); ch->Print("file.pdf["); for (int i=0;i<npeaksFound;i++) { sprintf(histname,"histo%d",i); min = xpeaks[i] - 5; max = xpeaks[i] + 5; …

[image] Converting numbers into string ROOT Hi, I am looking for an easy way to convert numbers (Int_t, Double_t) into strings. What i want to do is to create dynamical columns in my ntuple and fill them. Something that should look like: string nameA=“ColumnNameA”, name…

If pointers to the canvases are stored in c[] you can do: for (int plot_um=1; plot_num<=number_of_plots; I++) { c[plot_um]->Print(Form("file%d.pdf", plot_um)); }

I tried using an array for canvases, but it gave me an error. Here is what I have - Double_t min, max; TH1F *myhist[npeaksFound]; TCanvas *ch[npeaksFound]; char *histname = new char[npeaksFound]; for (int i=0;i<npeaksFound;i++) { sprintf(histname,"histo%d",i); min = x…

If you create new canvases in a loop that way you do not need an array of TCanvas. The following is enough: Double_t min, max; TH1F *myhist[npeaksFound]; char *histname = new char[npeaksFound]; for (int i=0;i<npeaksFound;i++) { sprintf(histname,"histo%d",i); min = xpeaks…

That worked like a charm. Just one more question, is there a way to create a single pdf file for all these plots and save them together? I read a few comments and I am trying something like this- ch->cd(); myhist[i]->Draw(""); ch->Print(Form("file%d.pdf(", i)); ch->Print(Form("file%d.pd…

Oh, thank you so much! @couet This worked so well! You’re the best :smiley:
