Hi
I have a simple question. I need to quickly check root files and I need to superimpose different plots with different color or marker from root command line.
See below the example with cernstaff.root
ROOT 5.34/34 (v5-34-34@v5-34-34, Oct 02 2015, 16:30:37 on win32)
root [1] TBrowser c
root [2] T->Draw(“Age:Dision”,“Nation==“FR””,"");
Error in TTreeFormula::Compile: Bad numerical expression : “Dision"
Info in TSelectorDraw::AbortProcess: Variable compilation failed: {Age:Dision,Nation==“FR”}
root [3] T->Draw(“Age:Division”,“Nation==“FR””,”");
root [4] T->Draw(“Age:Division”,“Nation==“IT””,“SAME”);
root [5] T->Draw(“Age:Division”,“Nation==“CH””,“SAME”);
root [6]
I would like to plot for instance the Italian nationality with a different color and a different marker type on the same canvas. Same for CH, or GE etc…
Can you let me know how I can quickly do this?
Thank you
