Hello Rooters,
I have a 1D histogram of, say for example z vertex (+,- 60 cm). However, in my analysis I only use +- 30 cm. So I want to color only that range in my histogram to show the z vertex range used in the analysis. Can anyone help me how to do it?
Thanks very much in advance.
Regards
Monika
