Re: Longitude label at greenwich meridian
Hi again,
Well, there's aways more than one way to think about these things.
I received a suggestion for a way to wipe out that extra E, if you
want. If you're running version 5.53 of Ferret, you can put a
white polygon - in the right shape and size to cover over that E.
(v5.53 had a change that lets us plot polygons outside the plot box).
An example:
yes? use coads_climatology
yes? shade/x=-20:20/y=-20:20/L=1 sst
yes? ppl window off
yes? poly/over/pal=white/nolab/noax {.3,.3,.8,.8}, {-22.5,-21,-21,-22.5}
The /noax keeps Ferret from redrawing the axis, which would
put the label E back on. One could get fancy and use symbols
to define the location of the polygon (SHOW SYMBOLS after
making the plot lists useful symbols like XAXIS_MIN and
XAXIS_MAX which we could use to get the right location
automatically.
Again, this is just a workaround; we'll make the change in the
next release so that 0 gets no E or W label.
