Hello rooters, i got a histogram: TH2F *LShape06 = new TH2F("LShape06","LShape06",100, -1.,20., 100, 0, 30); I want to fit a profile of it, so i do: TF1 *f1 = new TF1("f1","[0]+[1]/x+[2]/(x^2)",0,20); TProfile *LShp06 = LShape06->ProfileX("",-1,20); LShp06->Fit(f1,"IM","",0.2,10); It works great except that the y-axis of the profile ends at 7, while the y-axis of the original profile goes to 30.... Anybody has any idea what to do? Best regards, Mariusz
