Re: [ferret_users] symbols LABZ, LABT as LABX, LABY

["William S. Kessler" <william.s.kessler@xxxxxxxx>]

Yes, but a caution.

This works fine on the first plot, but subsequent plots on different  
axes can produce inconsistencies. For example a SHADE plot might need  
only one of the LABn (e.g. latitude), but a line plot might need two  
(latitude and longitude, as in Ansley's example). Then the presently- 
unused LABn will be sitting around with its previous definition. This  
might lead to an incorrect label if you start using these by hand  
(Ferret will always know which axes are in use but you might not).

Note that these symbols (and other symbols you might define) can be  
combined:

label ... ($lab($labnum_y))   ! the latitude label
