Dear Dai,
I see. Well, I have passed this information to engineering. They will take a look at it.
As a workaround, I think the following can help:
READ_JPEG, FILEPATH('Day.jpg', $
SUBDIR=['examples','data']), daymap
; Define the latitude and longitude data for the contour.
longitude = FINDGEN(360) - 180
latitude = FINDGEN(180) - 90
cntrdata = SIN(longitude/30) # COS(latitude/30)
; Display the global image.
map2 = IMAGE(daymap, $
LIMIT=[-90,-180,90,180], GRID_UNITS=2, $
IMAGE_LOCATION=[-180,-90], IMAGE_DIMENSIONS=[360,180],$
MAP_PROJECTION='Mollweide')
; Hide the original map grid:
grid1 = map2.MAPGRID
grid1.LINESTYLE = 6
grid1.LABEL_SHOW = 0
; Create a NEW map grid.
grid2 = MAPGRID(COLOR="red", $
TRANSPARENCY=0, $
LONGITUDE_MIN=-180, LONGITUDE_MAX=180, $
LATITUDE_MIN=-90, LATITUDE_MAX=90, $
GRID_LONGITUDE=10, GRID_LATITUDE=10, $
LABEL_SHOW=0)
end
I hope this helps for now.
Cheers,
Fernando
