Normalize to bin content

ROOT
1

Dear all,

I fill a weighted histrogram

histo->Fill(value, weight);

and want to normalize to the actual number of entries in that bin, i.e. multiply each bin content by 1/entries_in_that_bin.
Is it possible to access the number of entries and the bin content seperately (for unweighted histograms they are equal) or do I have to switch to TGraph ??

Thanks in advance,
Manuel
