Thank you for this fast, complete, efficient and instructive answer.
Actually I find that changing the value of cs: did mainly what I was
looking for just after having sent my e-mail.
I am a bit surprised there is no "shortcut setting", "easy option" for
this. Is there a way to define this "axis y label/.style" setting
somewhere "globally", so I do not need to add it for every graph I do?
Thank you.
Cheers,
Xavier
