of "ValueError: width and height must each be below 32768" which
apparently comes from matplotlib/backends/backend_agg.py, the RendererAgg
(whatever that is). I should point out these are plots which worked
before. Apparently it has something to do with adding axes_labels,
because without them, this problem does not appear. Did something get a
LOT bigger on the axis labels?

There might be a bug in that. Can you post an example?

I figured out what the problem was. I'm setting the x-axis label
y-coordinate to y=0, which is obviously wrong if y=0 is not in the
picture. I'm doing a similar thing with the y-axis label. I've emailed
the matplotlib list for help on getting the right matplotlib transform to
get the label to be offset from the actual axis in the picture.
