Re: Rebinning of histogram

Dear Chris and Margar,

Thanks for your help.

But I think I didn't formulate
my question in right way.

Is it possible to rebin the one dimensional (already existing) histogram or just fill it in such way that the errors in each bin (for bins with not equal sizes to each other) would be the same or equal to the same value?

Thanks,
Hayk.

PS. I think I hastened with question because the problem might don't have such solution to be implemented for general use.
