[ROOT] Q2: Tree and Histograms

Dear Rooters,

I want to be able to create histograms on line from a Tree structure. In the
manual, I read it seems that I need Tree->GetEntries() to be able to fill
my histograms. I guess this is the solution when the Tree is of fixed size. But
in this case, my tree would be filled continuously by the data stream (I don't
know how yet), how can I fill continuously my newly created histograms
without having to specify the number of events to be processed ?

Thanks,

Fred
