Hi,
There is no automatic way to get this in ROOT.
This posts can help you: TF1 intersection - #2 by brun
where you need to replace one of the TF1 with the TH1. Ini case of multiple interceptions the code above needs to be adapted and one need to search in different ranges for the multiple intersection points.
