I d'ont create at all any TApplication in my code but I can see
interactively my ntuple inside root:
here is my script which is simple:
{
gROOT->Reset();
c1 = new TCanvas("c1","plots",600,600);
gPad->SetBottomMargin(0.15);
gPad->SetLeftMargin(0.16);
TFile file("file.root");
hfcl->SetStats(kFALSE);
//titre
hfcl->SetTitleSize(0.05, "x");
hfcl->SetTitleOffset(1., "x");
hfcl->SetTitleSize(0.05, "y");
hfcl->SetTitleOffset(1.5, "y");
hfcl->GetXaxis()->SetTitle("l");
hfcl->GetYaxis()->SetTitle("l(l+1)C_{l}/2#pi (#muK^{2})");
hfcl->SetLineStyle(1);
hfcl->SetLineWidth(1);
hfcl->SetLineColor(13);
hfcl->SetFillColor(13);
hfcl->Draw();
hcl->SetLineColor(16);
cl->Draw("y:x","","same");
////////////////////
c1->Update();
}
running it, I don't see the "cl" ntuple drawn.
Interactively I type the
cl->Draw("y:x","","same");
command, and the points appear on my canvas
