Hello, I wrote a small application in which I have some TGraphErrors and I would like to fit them with a pol1. I call TGraphErrors::Fit with the "Q" option, but still the very first time that I call it, I get this output: ********** ** 1 **SET ERR 1 ********** Does this mean that I'm doing something wrong? If not: is it possible to avoid this message? Thanks, Andrea Di Simone.
