flight time measurement: no fitline shown #42

Closed aschulzdesy closed 9 years ago

aschulzdesy commented 9 years ago

when activating the flight time measurement and clicking "fit" no fitline is shown, only the triangles on top of the histogram. muonvelocitydistribution_fit

achim1 commented 9 years ago

The problem is that the fit is bad -> it basically failed and is not even able to calculate its chi squared/ndf ("nan"). Not sure how to fix it at the moment

achim1 commented 9 years ago

Fixed! The Gaussian was broken (had only two instead of three parameters as intended). This fix should go to any branch

Hi Achim, in which version is this fixed? I had a problem today with version 2.0.10. See plot: velocity_nofit

2.0.11 ^^ ..and we are at 2.0.12 now..
