Hi rooters, Is there a simple way of fitting a user defined function to several histograms at the same time? The problem is rather usual : I try to fit some parameters using several observations summarized in different histograms (that may not be compiled: e.g. fitting the parameters of a resonance using several channels). Of course, what one would do in a non-object-oriented framework is just to fetch data from all histograms into arrays and fit them...
