Hi all,
I saved canvases in root file.
Now I would like to merge. e.g., two canvases from two root.file.
I easily access and draw each canvas separately. But how to merge?
In the code it was not like simple histogram which was saved to canvas and that canvas to root.
Can I merge for example 2 canvases in that case? Or I need to have histograms first and plot 2 hists in new canvas? But If yes, I don’t know how to take histograms from the canvases.
Thanks for the help
This is code I use:
TFile *f = new TFile("Canvas100.root");
f.ls();
TCanvas *c = (TCanvas *)f->Get("MyCanvas100");
c->GetListOfPrimitives()->Print();
// Draw canvas
c->cd();
c->Draw();
Below is the print from the canvas:
//==================================================================
TFile** Canvas100.root
TFile* Canvas100.root
KEY: TCanvas MyCanvas100;1 MYCANVASTEXT
