[ROOT] TProfile with variable bin sizes

Hi ROOTers,

I need a variable bin size profile, and so I have had a look on the code 
to see what it makes. The problem is that ROOT takes the mean and the 
standard deviation only along the y axis, but not in the x axis. Later on 
I need to fit the points (x_{m}, y_{m}), where x_{m} is the mean of the 
points alog the x axis, and y_{m} the mean along the y axis, weighted eith 
the error along the y axis.

Does anybody know a way to do it, without having to use a TGraphErrors and 
to calculate all the errors manually?

Thanks in advance,
