a probably rather stupid question to which I can't find an answer:

I have a bar chart, and I want to present which bars are significantly
different by placing a line with an asterisk above then (similarly to fig. 3
in: http://jnm.snmjournals.org/content/46/4/574.figures-only).

Does anyone have a reference where can I find some instructions how to learn

Thanks a lot!
