Mary,

Unfortunately, setting FreeAspect had no effect in my example.

By the way, I wouldn't like the diagram to be widened, I'd just like the
titles on top to be pulled apart. That is, I'd like the whole canvas to
become wider. The diagram should ideally stay at its current aspect
ratio in the center. However, I'm currently unable to change the canvas
width at all - it always seems to be adjusted to match the (unchanged)
diagram width.

Perhaps I should indeed switch to lower-level drawing routines, but this
problem of making the plot wider to accomodate a longer title seemed
conceptually so simple that I thought that maybe I was missing something
obvious. I'm happy with the wrf_xxx output apart from this little detail.

Jan Ploski
