Try this sample code...

data = dist(46) ; create data
lons = indgen(46)*8. ; longitudes
lats = indgen(46)*4 - 90. ; latitudes
colors = indgen(25)+161 ; or whatever works for your color table

y1 = total(where(lats eq min(lats))) ; SH point
y2 = max(where(lats le 0)) ; Nearest-Equatorial point

map_set, -90, 0, 0, /stereo, limit=[-90,-180,0,180], /iso
contour, data(*,y1:y2), lons, lats(y1:y2), nlevels=25, /follow, /over
contour, data(*,y1:y2), lons, lats(y1:y2), nlevels=25, c_colors=colors,
$
/cell_fill, /over
map_continents
map_grid, latdel=30, londel=30, glinethick=1, lonlab=0

This is not a "perfect" plot, but those are VERY HARD to come by
using IDL mapping routines and with the cheesy contour program they
provide. Very unlike NCAR Graphics, at at 10 times the price!!
What a bargain. ;-(

Analysis? Yes.
Visualization? Maybe.
