[Histogram] Variable bins Size in order to have the same number of entries for each bins

[Zardoz]

Hi !

In order to have equal-statistics bins, i want to modify the size of each bins of my histogram in order to have the same number of entries.

I know i have to use the method TH1::Rebin() and probably GetBinContent() And FindBins() but i don’t really know how to start for create my array of new bins.

Is a method already exist for this ? I know that’s common for physicians to transform a histogram like that…

Thanks in advance !

Rebin histogram

Hi, I need to rebin histograms of my macro. Running I would like a bin width =1 …Looking the plot that I got by running the macro I see the range is [-600;600], so I wrote: `htemp->Rebin(1200); htemp->Scale(1/htemp->Integral());` But it didn’t work, so I also tried to force the x range writing htemp->Rebin(1200); htemp->SetAxisRange(-600.,600.,"X"); htemp->Scale(1/htemp->Integral());…
