This code produces a series of rainbow colored lines both on
the display and in a PostScript file.
PRO Test
Loadct, 13 ; Rainbow colors
x =findgen(256)* 0.8/256. + .1
Window, XSize=800, YSize=400
for j=0,255 do plots, [x[j], x[j]], [0.1, 0.9], Color=j
thisDevice = !D.Name
Set_Plot, 'ps', /Copy
Device, XSize=10, YSize=7, XOffset=0.5, File='test.ps', $
YOffset = 10.75, /Inches, /Landscape
for j=0,255 do plots, [x[j], x[j]], [0.1, 0.9], Color=j
Device, /Close
Set_Plot, thisDevice
