I don't know if you know it but IDL has the NORM_COORD function that
scales [min,max] values between [0,1], and also exist other more usefull
routine from David Fanning called NORMALIZED that normalizes the values
between any other values: [0,1] or [-1,1] or anyone.
Bye.

Hey Antonio,
Thanks for your answer.
I worked it out using the normalized coordinates. It was a bit of a
hazzle calculating everything in normalized coords by accounting for
both the aspect ratio of the image and that of the printer page, but
now it works.
Thanks
Soren

(Sorry for my poor english, I don't understand very well.)
Try with IDLgrPrinter if you want to print your graphics to a printer
device.
Otherwise (if I am mistaking) try to normalize your coordenates so that
your image and colorbar are put on the appropiate positions.
Sorrr, if this is an stupid answer :)
