Hi,
This question deals with having ROOT put fits to data I have stored in an TNtuple. For example, I have Bfield, temperature, and frequency stored for each entry (leaf?) in the ntuple. What I would like to do is draw say frequency versus temperature, and then have root try various
mathematical fits to the data. The drawing part I can do, but I have been unable to really get anything from the refernce documentation about the Fit() function for TTrees. Can someone provide me with an example that would show me how to apply a particular formula fit to data I have stored in Tntuples?
Thanks, Andy
