==========
Hatch demo
==========

Hatches can be added to most polygons in Matplotlib, including `~.Axes.bar`,
`~.Axes.fill_between`, `~.Axes.contourf`, and children of `~.patches.Polygon`.
They are currently supported in the PS, PDF, SVG, OSX, and Agg backends. The WX
and Cairo backends do not currently support hatching.

See also :doc:`/gallery/images_contours_and_fields/contourf_hatching` for
an example using `~.Axes.contourf`, and
:doc:`/gallery/shapes_and_collections/hatch_style_reference` for swatches
of the existing hatches.
