OK, so this behavior is the 'normal' one. I had been used to the previous one, that better fitted(!) my needs: Fit with option '0' didnt draw anything, so I could have a method to fit my spectra and computing values etc. Without this option, the Fit() method *immediatly* perform a 'Draw()' of the histogram, which I dont want (because i'm computing not displaying at this time). But next, when in a display method I do a hist->Draw() the fitted function appeared naturally. Now I think I have to manually loop over the functions and expicitly draw it. Yannick
