You can explicitly specify the page location of each plot using the
position Keyword in the call to plot. Set the !p.multi, and then
use something like:

plot,y,position=[1000,1000,6000,6000],/device

This will use the Postscript device coordinates (1000 units = 1cm on the page).
The lower left corner is 0,0 and the 4 elements of the array in position are
x0,y0,x1,y1 This allows for very precise control of the plot positioning and
aspect ratio.

If all else fail, you should be able to display the plot on the screen,
and then do a tvrd() call, you can then write the saved array to
a tiff image file.

Hope this helps.
