Hi~ guys. I have a problem here. I have a small program doing a
contour plot. But is just show me the background, not the data. I
guess there is something wrong with the colors. Can anyone help?
Thanks

lat=fltarr(75)
lon=fltarr(75)

latstep=(34.3842-31.6985)/74.0
lonstep=(121.5581-118.3524)/74.0

for i=0,74 do begin
lat(i)=-31.6985-i*latstep
lon(i)=118.3524+i*lonstep
endfor

print,max(lat),min(lat)
print,max(lon),min(lon)

device,decomposed=0
!p.background = 255
xs=600
ys=600
window,xsize=xs,ysize=ys

contour,inits,color=0,xrange=[min(lon),max(lon)],yrange=[min (lat),max
(lat)],xtitle='longtitude',ytitle='latitude',title='Sensible heat
flux'
