If you please, is there any measurment of the fitting quality that dosnt depend on the uncertainty in the histogram bin, i know the chi^2 but the issue is that chi^2 fitting is dependant on the bin error and my histogram dosnt have uncertainty in it…

Thanks a lot in advance

See, e.g., the “W” and “WW” fit options in the TH1::Fit method description.

Many Thanks, but how to apply this if i want to calculate the simlarity between two histogram, i. E. I will use one histogram to fit another histogram, not a function to fit histogram

Why don’t you use the common histogram-similarity measures, like Kolmogorov-Smirnov, chi2, etc?
