Hello~

I want to overlap contour lines on a map.
However, I think it doesn't match exactly (I checked the gridlines)..
especially, as it goes to the edge..
Could someone know how to fix it?
Here is an example...

;-------------------------------
lon = FINDGEN(91)
lat = FINDGEN(115)
x = 17.0 + lon*(1/6.0)
y = 23.0 + lat*(1/6.0)

seed=1L
temp = sin(x)^2 * cos(x)
z = DIST(91,115)

LOADCT, 39

WINDOW,1,TITLE='WORLD MAP',xsize=800,ysize=900

CONTOUR, z, x, y, /Follow, position=[0.1,0.1,0.9,0.9] $
, NLevels=20, XStyle=1, YStyle=1, /NoErase, /FILL ;$
MAP_SET, /CYLINDRICAL, LIMIT=[23.0,17.0,42.0,32.0], /CONTINENTS $
, /HIRES, Mlinethick=1., position=[0.1,0.1,0.9,0.9] $
, /Noerase;, /ISOTROPIC
MAP_CONTINENTS, /HIRES,color=255, /FILL_CONTINENTS, /CYLINDRICAL ; /mercator
MAP_CONTINENTS, /COAST, color=0, /HIRES, /CYLINDRICAL ; /mercator
MAP_GRID, charsize=1.25, color=100 ,latdel=2, londel=2 $
, /BOX_axes, GLineStyle=2
;-------------------------------

Thank you.
Sincerely.

Son
