John, it looks centered with KGhostView (debian sarge)
Thanks for the input. I should have mentioned, I made the figure on
my linux server and then scp'd it over to my powerbook on which I'm
working. When I view it in preview, it is first converted over to pdf
and this may be where the bug is, not on the mpl side.
When I open it in ggv over X11 it now looks centered, but it appears
to be b4 paper 10.11 x 14.33, even though I have selected letter in my
rc file and as my default in ggv. I guess this is the spill-over
effect Darren described earlier, in which a larger papersize is
selected if you he figure doesn't fit on the default papersize.
Yep, I just confirmed by looking in the ps file, it is selecting b4.
Anyone else have an opinion on the desirability of auto-papersize
