TH1F::Scale - "width" option


I read here:

that the TH1::Scale() method takes an option as the second parameter. If the option “width” is set, then it will divide each bin’s content by the bin width.

Unfortunately I don’t see this implementation – I only have:
root [0] TH1::Scale(
void Scale(Double_t c1 = 1)

Is this feature available somewhere else now? I’m using ROOT 5.18.00b.


This option was only implemented in 5.20 (please read release notes).
I suggest you to move to version 5.22
