Error bar not computed in Root with AthAnalysisBase2.4.11

Your script with 6.07/07 (master) on Mac gives me the attached picture.


I am debugging my script. I’ll get back to you soon.

Ok finally found the problem. In my script I was setting the histogram SetLineWidth (0).

In ROOT version 6.02 the default linewidth is 1 root.cern.ch/root/html602/src/T … tml#CXBFEC Line 59

But in ROOT version 6.04 and higher the default is 2 root.cern.ch/root/html604/src/T … tml#CXBFEC same at line 59.

So error bars line never drawn when going to 6.02 to 6.04.

Thanks a lot for your help. I have fixed it now. It seems working. But If there is some problem I’ll ask you.

Thanks

Ah yes ! Settling width 0 hides the lines …
