Comment:
He's a solution to this problem. Part of the reason the plots were empty
is that the function `setup_for_eval_on_grid()` in `plot/misc.py` outputs
plotting steps as an absolute value, not a signed value. I've removed that
and modified the doctests accordingly, but six other plotting files use
that function in addition to `plot.py`.
All plotting doctests pass and documentation all builds. I scanned all
seven plotting documentation HTML files that use
`setup_for_eval_on_grid()` and didn't see anything strange, but other eyes
need to look at them closely.
Adding Javier to cc list since he's been working on plotting examples and
might spot something wrong.
