Hello Root family,
I have a histogram to which I fit a pedestal + gaussian. After this what I want to do is to re-plot the histogram but subtracting the pedestal that was obtained. Does anyone know how to do this in a simple way?
Thanks.

If you subtract the “pedestal”, some histogram bins will probably have “negative” content. ROOT will run amok, if you try to play with it afterward.
@Wile_E_Coyote No problem with the “negative” content, I just want to use it to compare with other plots, it’s more for a visual aid.
I went into the “ROOT will run amok” but I didn’t find what I should use to remove the pedestal.
You can create a “pedestal” function (extracting its parameters from the fit) and then use: TH1::Add
