Here you go. Took me five minutes, but tweak as needed. :-)

PS_Start
cgLoadCT, 4, /Brewer, /Reverse
cgdisplay
p = Fltarr(4, 4)
p[*,0] = [0.10, 0.55, 0.45, 0.85]
p[*,1] = [0.55, 0.55, 0.95, 0.85]
p[*,2] = [0.10, 0.10, 0.45, 0.40]
p[*,3] = [0.55, 0.10, 0.95, 0.40]
cbp = FltArr(4,4)
cbp[*,0] = [0.10, 0.90, 0.45, 0.93]
cbp[*,1] = [0.55, 0.90, 0.95, 0.93]
cbp[*,2] = [0.10, 0.45, 0.45, 0.48]
cbp[*,3] = [0.55, 0.45, 0.95, 0.48]

FOR j=0,3 DO BEGIN
cgContour, cgDemoData(18), /Fill, Position=p[*,j], NOERASE=(j NE 0)
cgColorbar, position=cbp[*,j]
ENDFOR
PS_End, /PNG
END

Cheers,

David

> I am creating some postscript files with 4 contour plots each using !p.multi. I would like each plot to have it's own colorbar positioned with it as they all have unique ranges. I've dug around and found that use of the POSITION keyword is not compatible with !p.multi. Is there another way for me to position each colorbar with it's corresponding plot, instead of all on top of each other and in the middle of the plots? Or am I doomed to use the position keyword for every
plot and every colorbar? This seems daunting to implement; I have my cgContour and colorbar command embedded within a set of for loops for ease of plotting many many parameter "slices" of a rather large data grid.

You are pretty much doomed.

Acutally, if it took you 30 seconds to rough out where
four plots are suppose to go in a window, I think you would probably
be taking too much time, but maybe we have different ideas
of what is "daunting". :-)

Cheers,
