[Barbaglia, Guido (ESA)]

I've missed William's e-mail indeed, I've tested it and works great, thanks a lot!!!

Many Thanks
Guido

Guido

You missed William's e-mails, which solved the problem:
use

  yaxs="i"


in second call. Also, William made the good point that you can rather
just use lines() in second call.

Good William!

Basically, what I need to do is to plot different series on the same chart using different types of plot (lines, barplot, ...) and it is fundamental that the various charts have the same reference system. I hope that someone in the list is able to fix my problem!
