of the picture, put ticks on both sides, and if it is on the side of the
picture, put ticks facing inwards?

I thought that was already the convention, but it was screwed up in this
plot. I think that in general ticks on the right/top are okay, except
where the axis is beyond the entire plot. Probably that isn't the case
for this plot, but it still looks weird.

scientific notation comes into play, matplotlib doesn't label correctly.

No, I mean that the labels are WRONG. The scientific notation only shows
up at the very top e.g. 2e8 or something, and the rest are just 1, 1.5,
etc; certainly the fourth power function does not stay around 1, 1.5 very
long. Having 2e8 or 1.5e8 is okay, of course.

to get this good. Assuming we actually want to do so, that is - is it
more effort than its worth? Maybe the matplotlib upgrade could be a
separate ticket, because that is certainly worthwhile and presumably
doesn't cause any problems.

at least, close enough to a sage-devel discussion) that it's not worth
trying to package 0.99.0 separately. Most of the reason why 0.99.0 is
worth it is for these changes, I think.

Okay.
