TH1D from TH2D's

Dear all,

I am doing an analysis job where I create the same 1D histogram for several bins of a reference variable. I was wandering if it is possible to do this with a TH2D, instead, but I should have the possibility to take a single "row" of such TH2D to retrieve the corresponding TH1D with only the entries in that row, because I think that this is less memory demanding, and it could allow to have a very large number of bins in both dimensions of the histogram, which would be of great advantage to me.

Is this possible in an automatic way?

Hope that the question is clear.

Thanks, cheers
