I do have some TGraph objects of various sizes but in similar scales, and their versions smoothed with various algorithms.
Could anyone please give me an idea on how could I subtract pair of TGraphs to draw the smoothing residuals easily? I am trying to come up with “automatic” smoothing algo choice and parameters tuning criteria for some measured data at hand…
Thank you very much in advance!
Sincerely,
Eugene.
OK, closed! It was easy, I just haven’t dealt w/TGraphs all that much before. GetPoint/SetPoint do all that is needed. Interpolation is useful if comparing two different ones. Sincere thanks to everyone!
