Hello,
it is well known that TH1::Add method is protected against any attempt to add two histograms which do not match in the binning.
I have the impression that this constraint could be relaxed for histograms which have the kCanRebin flag set and which were booked with the same original binning and, indeed, were (automatically) rebinned at the filling time. When such a pair of histograms have to be added they can be rebinned in order to match each other and then added.
So, I’d like to know if:
-
what I am saying make sense,
-
if it is already like that in root (I vaguely remember that i tried once and it did not work)
-
if it is somehow foreseen to have such a feature in future releases
-
anyone has ever tried , privately, to do something like that.
Thanks in advance and cheers Andrea
