Hi Rene,

what is strange?

In a TProfile you show
y_i=sum(x_j)_i/N_i
being i the bin-number and x your observable. N_i the number of entries in this bin.

What I want is a function returning:
I=sum(y_i)*N_i (=sum(sum(x_j)_i)
instead of
I=sum(y_i)
as integral.

Sometimes it is usefull to have this number also if I display a profile of the observable.

Thomas.
