Re: Plot with multiple y axis

Masha,

Thank you so much! This answers one of my questions in the email.
Do you know anything about the other question, that is, how can I add
2 axes on the left and 2 on the right of a plot? Is it possible to do
that in NCL? I have done it with three axes, as in the script I sent.

Thanks!

Michel
