I think that you may also draw *only one* map projection, but by adding a second grid to the map:

mp1 = map('Equirectangular', CENTER_LONGITUDE=180, $
POSITION=[0.1,0.1,0.90,0.75], $
LABEL_POSITION = 0, BOX_AXES=1, $
GRID_LATITUDE = 30, GRID_LONGITUDE = 45, $
ASPECT_RATIO=0, LIMIT=[-89.99, 0, 89.99, 360])
mp1['Latitudes'].label_angle=90
mp1['Longitudes'].label_angle=0

grid = MAPGRID( $
LONGITUDE_MIN=0, LONGITUDE_MAX=360, $
LATITUDE_MIN=-90, LATITUDE_MAX=90, $
GRID_LONGITUDE=45, GRID_LATITUDE=30, $
LABEL_POSITION=1)
foreach g,grid.latitudes do g.label_angle=270
foreach g,grid.longitudes do g.label_angle=0

alain.
