Annoyance #1:
If I do:
WINDOW, XSIZE = 400, YSIZE = 400
MAP_SET, 90, 0, -90, /AZIMUTHAL, LIMIT = [0, 0, 90, 360], /ISOTROPIC, $
/GRID, GLINESTYLE = 0L, LATDEL=30, LONDEL=90, /CONTINENTS
I get a polar-equidistant plot of the northern hemisphere. It has the
annoying rectangular border, which is supposed to be 1% larger than the
map. In this case, however, there is a small space between the map and
the border on the left and right sides, but the top and bottom edges of
the map are flush with the border. (So is it isotropic or not?)
Anyway, if I turn off the border with:
MAP_SET, 90, 0, -90, /AZIMUTHAL, LIMIT = [0, 0, 90, 360], /ISOTROPIC, $
/GRID, GLINESTYLE = 0L, LATDEL=30, LONDEL=90, /CONTINENTS, /NOBORDER
The map gets a little bit larger (as expected), but now a few lines of
pixels at the top and bottom of the map are cut off!
Anyone know why it does this or how to fix it?
------------------------------
Annoyance #2:
I would like to have the title and outermost latitude ring of the map be
black, while the interior latitude and longitude lines are, say, gray. So
I try:
MAP_SET, 90, 0, -90, /AZIMUTHAL, LIMIT = [ 0, 0, 90, 360], /ISOTROPIC, $
TITLE = title
MAP_CONTINENTS, COLOR = 64
MAP_GRID, GLINESTYLE=0, LATDEL=30, LONDEL= 90, COLOR = 64 ;Draw gray grid
MAP_GRID, GLINESTYLE=0, LATDEL=90, LONDEL=360 ;Draw black grid
But MAP_GRID insists on drawing at least one longitude line, in this case
along the Greenwich meridian.
Anyone know how I can turn that off?
------------------------------
Annoyance #3:
If I make a simple global cylindrical-equidistant map:
MAP_SET, 0, 0, /CYLINDRICAL, LIMIT = [-90, -180, 90, 180], /CONTINENTS, $
TITLE = title, /NOBORDER
MAP_GRID, GLINESTYLE=0, LONDEL=90, LATS=[-89.99, -60, -30, 0, 30, 60, 89.99]
The rightmost meridian (along the dateline), and sometimes the leftmost
meridian, are not straight lines!
