Thanks for the reply. I should have been more explicit in saying I am
trying to do a perspective view of 4 parallel planes from somewhere
above and off to the side. I figured out a way to do it using the t3d
command and keyword.
for lev=1,4 do begin
z=.25*(lev-1)
xoff=.15-.05*lev
t3d,/reset,rot=[-65,20,0],translate=[xoff,0,z]
map_set,latcen,loncen,/cyl,/grid,/cont,$
limit=[lat1,lon1,lat2,lon2], $
/label,latlab=lon2-2,lonlab=lat2-2,$
position=p,/noerase,/t3d
endfor
I had to fiddle with the z offset to get them to line up vertically since I
couldn't figure out the right rotation to use.
I also got a reply from Jim Pendleton of RSI explaining how to do it using
Direct Graphics and Object Graphics.
