Hi,
I am following this example for doing a linear fit to a 2D histogram
root.cern.ch/root/html/tutorials … t2d.C.html
with only modifications to get the fit information with a TFitResultPtr.
What I wanted to know is if there is any way of adjusting the line colour and width of that fit. I saw something about ‘goption’ in the function definition but was not sure if that could solve the problem.
Thanks,
Hardeep
