Here is my landscape device statement, if it helps at all.
device,filename=outputfilename,xsize=8,xoffset=1.5,yoffset=1 1-2,ysize=5.5,/i
nches,/landscape
Cheers,
bob

The eps file is produced in Landscape mode, by making the page offset
bigger I have managed to get ghostview to display all of the eps file
correctly, which leads me to suspect my XOffset and YOffset calculations
are not 100% correct when doing Landscape plots ... so I'm surprised the
PS plot (for the old page offset) turned out o.k.
cheers

Hi Stuart,
here are some guesses which may help with your ps problem.
What is your device line? Mine is for instance:
set_plot,'ps'
device,filename=outputfilename,xsize=5,xoffset=1.5,yoffset=2 ,ysize=7.45,/inc
hes
The bounding box "seems" to be set on that statement
(ie I can change the bounding box by changing the xsize and ysize comments
there, but modifying !P.region has no effect on the bounding box.)
As to why your second plot does not show up, are you plotting in landscape
mode?
It is possible to plot off the page if you do this, and not set up the sizes
and offsets
correctly.
Are you sure there is only one page of postscript output?
Depending on how you create the second plot, IDL may put
a "newpage" command in, in which case you may have to
apply "noerase" commands (probably in your first plot command,
to suppress a newpage after it completes).
If this is the case, I can give an example of how that works.
I'm using Gsview32.exe version 2.8 on WinNT.
In Ghostview Under Options click on "show bounding box" to see a
dotted line indicating the bounding box.
Cheers,

PS If these guesses don't help, drop me a line with
your IDL code that produces the offending ps, and
maybe I could straighten it out.
