I have a 2d TGraph object and want to fit / smooth it (get rid of the wiggles etc), see graph attached. I generated this graph by using a TH2F object and the Smooth(1) option (unfortunately Smooth(2) is not working for 2dim histograms) and extracted its contour.
I also found this topic (Smooth TGraph) but its not helping because I already used the Smooth option for histograms.
Is there something else implemented in ROOT I could use for further smoothing?
Thanks in advance
