Comment (by dimpase):
RTFM :-) The most meaningful output seems to be with `contours=0`. The
docs of `contour_plot` say
{{{
* "contours" -- integer or list of numbers (default: "None"): If
a list of numbers is given, then this specifies the contour
levels to use. If an integer is given, then this many contour
lines are used, but the exact levels are determined
automatically. If "None" is passed (or the option is not given),
then the number of contour lines is determined automatically, and
is usually about 5.
}}}
and this explains why `None` gives you nonsense, usually. `contours=1`
give 2 contours, not 1, apparently there is a shift by 1 somewhere...
