Of course, you could use TVIMAGE instead of CONTOUR. This
wouldn't *fix* the problem with MAP_SET, but it would
extend the colors to the edge and maybe make it easier
to finesse the rest of it:
data = dist(181, 91)
x = scale_vector(findgen(181), -180, 180)
y = scale_vector(findgen(91), -90, 90)
ctload, 4, /brewer, NCOLORS=20
device, decomposed=0
map_set, /Cylindrical, Position=[0,0,1,1]
;contour, /overplot, data, x, y, Cell_Fill=1, nlevels=20
TVIMAGE, BytScl(data, TOP=19), Position=[0,0,1,1]
MAP_GRID
MAP_CONTINENTS
END
Cheers,
David
