TH1::Fit ... TF1::kNotDraw

[Wile_E_Coyote]

In the TH1::Fit method description, in the … Warning when using the option “0” … you “REDEFINE” the TF1::kNotDraw enum: const Int_t kNotDraw = 1<<9;
Maybe you could remove that line and simply replace ->ResetBit(kNotDraw); with the proper ->ResetBit(TF1::kNotDraw); in the example code given therein, or at least modify: const Int_t kNotDraw = TF1::kNotDraw;
