Statistics of a RooPlot from a RooMCStudy

Hello all.

I’m creating toys with RooMCStudy. Then I plot one parameter to a RooPlot. The question is how to extract the statistics of that histogram (mean, rms, etc). I’m using the rooplot->SetStats(kTRUE) but it returns same values that are certainly wrong…

Any ideas of what I’m missing?

Many thanks,
