Greetings.
How can I output the maximum value of the histogram (on the Y axis) without drawing?
My code doesn’t help.

c = ROOT.TCanvas()
myFile = ROOT.TFile.Open(“/home/erg/2022.12/2022.12.01/Dec01031235.root”)
Tree = myFile.Get(“FADCData 882”)
Tree.GetMaximum(“Channel0”)

_ROOT Version: 6.26/10
_Platform: Ubuntu
_Compiler: pycharm community

Hi @Fredrih ,

Please see the TH1 documentation for information on how to retrieve the maximum value of an histogram. Also, read TTree documentation to understand what your call to TTree::GetMaximum in your snippet is doing.
Cheers,
Vincenzo
