[Matplotlib-users] matplotlib._cntr.Cntr gone in 2.2

[Thomas Caswell]

Fabien,

I suggest looking at skimage (
http://scikit-image.org/docs/dev/auto_examples/edges/plot_contours.html )
for contouring code.

If you are absolutely dependent on that API, the source is available from
previous releases and you are welcome to vendor or create a stand-alone
library (not sure how hard that would actually be).

Please do not use private APIs.  We can (and will!) change them with no
notice.
