Hi everyone,
I made some histograms, and now I would like to determine one X value where let’s say 90% of the histogram is less than this value.
Could someone explain me how to do it please, thanks in advance.
Cheers

Hi,

You can use TH1::GetQuantiles

See root.cern.ch/doc/master/classTH … a398675b8d
