[Matplotlib-users] cross hatching in contours?

[Jonathan S. <js...@cf...>]

I'm wondering if there is some way to do cross hatching as a way to fill
contours rather than colors (using contourf).  The only references to
cross hatching I see in the documentation are for patches type objects.
As far as I can tell, contour and contourf return objects of their own
type (contour.QuadContourSet) that do not have hatch as an attribute.

If it's not possible currently, how hard would it be to add that
capability to contourf?  What approach would you recommend?
