| After editting my mp_graticule script (as per http://www.pmel.noaa.gov/maillists/tmap/ferret_users/fu_2004/msg00685.html), this works great - thanks!

Send it " " for the first 3 arguments. That'll skip making any lines of longitude, and you can then just draw one line of latitude use etopo20
set reg/y=-90:-60
set grid rose
go mp_stereographic_south
go mp_aspect
shade/noax/nokey rose,x_page, y_page
go mp_graticule " " " " " " -60 -60 5 7
Or whatever your upper limit of Y is. The 5 is arbitrary, delta-y. You can also give it a " ". And I've sent in pen 7 which is a dark line, which I think looks nice, but you could skip that for the default thin black line. Ansley Paul Young wrote: Hi all,
Just wondering if there is a simple way to add a circle around a polar stereographic plot - i.e. a graticule just at the low latitude limit. I've tried using mp_graticule.jnl with lon_min=0, lon_max=360, lon_delta=360 (etc), but I can't get it to work. I've attached a picture which illustrates what I'm trying to do.
As always, thanks for any help,
Paul
