Hi,
I want to be able to show a histogram without its error and a fit to that histogram (even if it uses those errors in doing the fit).
Thanks,
Charles
[code]root [0] TH1::SetDefaultSumw2()
root [1] TH1F hist (“hist”,“hist”,10,0.5,10.5)
root [2] hist.Fill (3,3)
root [3] hist.Fill (4,5)
root [4] hist.Fill (5,8)
root [5] hist.Fill (6,4)
root [6] hist.Fill (7,2)
shows histogram with no error bars
root [8] hist.Draw(“hist”)
fits and shows histogram with error bars
root [9] hist.Fit(“gaus”)
fits and shows histogram with no error bars
root [11] hist.Fit(“gaus”,"",“hist”)
shows fit and histogram with errors
root [12] hist.Draw(“fit same”)
[/code]
And for those of you who haven’t yet mastered Emacs rectangle functions but want to cut and paste the whole example at once:
TH1::SetDefaultSumw2()
TH1F hist ("hist","hist",10,0.5,10.5)
hist.Fill (3,3)
hist.Fill (4,5)
hist.Fill (5,8)
hist.Fill (6,4)
hist.Fill (7,2)
hist.Draw("hist")
hist.Fit("gaus")
hist.Fit("gaus","","hist")
