Error : L (Log Likelihood fit)

Hi, i’m trying to fit a series of data but root gives me this error:

L (Log Likelihood fit) is an invalid option when fitting a graph. It is ignored

Anyone can help me ?

Thanks

See the TGraph::Fit method description for the list of available “fit options”.
You may also compare them with the available TH1::Fit “fit options”.

I have seen these links but i still don’t know what to do

The invalid “L” fit option has been ignored. You don’t need to do anything.

Ok, but i want to fit this series of data, and root doesn’t give me any sort of fit.

Learn from the official “ROOT Fit Tutorials” (and / or “ROOT RooFit Tutorials”), and if you still cannot get it working, post your macro here and any required data files.
