And here I am trying to make direct graphics more object-like:
; Plot a map in one window
odg0 = obj_new('MGHdgWindow', DIMENSIONS=[400,400])
odg0->plot, '!p.color = 255 & !p.background = 0', /EXECUTE
odg0->plot, 'map_set', 0, 170, LIMIT=[-50,160,-30,180], /ISOTROPIC,
/MERCATOR
odg0->plot, 'map_continents', /HIRES, /FILL_CONTINENTS
; A line plot in another window (with different colours)
odg1 = obj_new('MGHdgWindow', DIMENSIONS=[450,350], RESIZEABLE=0)
odg1->plot, '!p.color = 0 & !p.background = 255', /EXECUTE
odg1->plot, 'plot', findgen(100000)
; Go back and add something to the map.
odg0->refresh
odg0->plot, 'map_grid'
