Producing decent eps plots for publication requires extensive control
over all aspects of the plot, such as the x- and y-sizes, the font
sizes, etc. I've always exercised this control using direct graphics.
The downside, of course, is what you see on the screen is not what ends
up in the eps file when you change the device--something we have all
asked to be fixed for so many years I've lost count. Once or twice a
year, I try to use itools to do publication quality plots. I just tried
again, and things have improved a bit, but not enough. Does anyone know
how to specify the x- and y-sizes of the bounding box in an eps file
written from an iplot window? All I can seem to get is 6"x4".

Exactly why I stuck with direct graphics - I decided that, for my
purposes, it was easier to cup/paste/modify code than to wrestle with
itools etc.
Best of luck,

Your approach is more or less what I already do in direct graphics. It
is just plain annoying that we all have to go through this complexity
to get the results we want and journal editors expect. That is why I
keep wandering back to itools every so often (and why I keep playing
with and moving toward matplotlib).
I've played some more with pp's suggestion about just setting the
aspect ratio and run into all sorts of complications. For example, the
margin keyword does not work consistently when combined with the
dimension keyword. I finally found that I can control the aspect ratio
exactly and adjust the margins by adjusting the viewplane_rect. This
was once a bit painful--there is code at Dave Fanning's web site for
doing it. Now it is much easier using the igetproperty and
isetproperty procedures.
