Try this
IDL> window
IDL> !p.position = [0.0, 0.0, 1.0, 1.0]
IDL> map_set, /grid, /continents, /isotropic, /noborder
Note that if the aspect ratio of the map does not match the
aspect ratio of the window, it will only be flush on two
sides.
For a polar map, for example, this works
IDL> window, xsize=400, ysize=400
IDL> !p.position = [0.0, 0.0, 1.0, 1.0]
IDL> map_set, 90.0, /grid, /continents, /isotropic, /noborder, $
/azimuthal, limit = [0.0, 0.0, 90.0, 360.0]
