Freaky Map Stuff [message #9547]

When I execute the following piece of code on my SGI Indigo 2 Impact
10000, running IRIX 6.2 and IDL 5.0,
the longitudes on the map do not run from -180 to -145, but from -180 to
-150. Does anyone know why?

Thanks in advance,

Charles Cavanaugh

pro testgrid
tek_color
limit = [-90, -180, 90, -145]
position = [0.05, 0.05, 0.84, 0.86]
map_set, 0, -162.5, 0, limit = limit, color = 4, position = position,
/cylindrical, /noborder, /noerase, /horizon
map_continents, color = 5
lons = [-180, -175, -170, -165, -160, -155, -150, -145]
lats = [-90, -45, 0, 45, 90]
lonnames = strtrim (lons, 2)
latnames = strtrim (lats, 2)
map_grid, latalign = 1.0, latdel = 45, latlab = lons(1), latnames =
latnames, lats = lats, $
lonalign = 0.5, londel = 5, lonlab = lats(1), lonnames =
lonnames, lons = lons, $
color = 6, label = 2
end
