Hi there,
I have a series a points in Cartesian coordinates (x,y) in a TGraph.
I want to plot those point into a TGraphPolar.
For this, I define Theta = Arctan(y/x) and r = sqrt(x^2+y^2).
Once I get my TGraphPolar, how can I fit the distribution ?
Should I create my own function ? how ?
If I stay in Cartesian coordinates, I simply use the Fit method with the “pol1” (as those point follow a line if Cartesian coordinates).
Thank you very much for your help.
