Hi everbody,

I would like to rein a histogram filled with percentages (like 0.45 and so on). Therefor I do not want the bins to be added up when rebinning but rather averaged. Is there an option to do this?

Thanks,

Emil

Hi,

If you are plotting averages, maybe what you want to look is the `TProfile`

class. See ROOT: TProfile Class Reference.

Otherwise, please be more specific and possibly provide an example

Thank you for your answer. I do not think the TProfile class is right for my problem. I have several histograms which I would like to divide, scale and add. All of them are â€śnormalâ€ť histograms but one is filled with values from 0 to 1. I have to rebin all histograms, but the one with values between 0 and 1 should not be added up as usual but rather averaged over the bin merged together. Until now I simply do this â€śper handâ€ť but was wondering whether there was an option in the â€śrebinâ€ť function to do this

`Int_t n = 5; myhisto->Rebin(n); myhisto->Scale(1. / n);`

Thank you for your reply. I need to calculate the error weighted average, which makes things more complicated. But I have now simply written a short function myself. Still thanks for your help!
