Dear Stuart,

we are using a plot envrionment to solve such problems.
There are many less or more difficulty things to know to make a
quadratic plot
in portrait or landscape.

The plot environment is described in my publication (german) 
with lots of examples.

http://www.fz-juelich.de/zb/text/publikation/juel3786.html

Some examples you can see at: 

http://www.fz-juelich.de/icg/icg1/idl_icglib/idl_source/idl_html/idl_work_idl_work.examples.category.htm#7

In our environment
plot.landscape=2 --> quadratic plot in portrait
plot.landscape=3 --> quadratic plot in landscape

plot.psflag=0 --> output in window on screen
plot.psflag=1 --> PS
plot.psflag=2 --> EPS


If you prefer your own plot routines then here is a bit of
the theory for EPS for a quadratic plot in portrait.



device,filename='idl',encapsulated=1,isolatin1=1,preview=0.,$
  yoffset=0. ,ysize=29.7  ,xoffset=0.,xsize=21.0,$
  /color, BITS=8,/portrait


now in norm coordinates the length of 5cm for X and Y Axes must be
calculated.

then this data must be given by the position keyword to plot.

Behind the plot and the device,/close the bounding box is to big.

With a command like 
epstool -b -c -ofile.eps good.eps

the bounding box will be set to the best size.

hope this helps

regards

Reimar
