6 | | -Hatching (pattern filled polygons) is supported currently in the PS, |
7 | | -PDF, SVG and Agg backends only. |
| 6 | +Hatches can be added to most polygons in Matplotlib, including `~.Axes.bar`, |
| 7 | +`~.Axes.fill_between`, `~.Axes.contourf
8000
`, and childern of `~.patches.Polygon`. |
| 8 | +They are currently supported in the PS, PDF, SVG, OSX, and Agg backends. The WX |
| 9 | +and Cairo backends do not currently support hatching. |
| 10 | +
|
| 11 | +See also :doc:`/gallery/images_contours_and_fields/contourf_hatching` for |
| 12 | +an example using `~.Axes.contourf`, and |
| 13 | +:doc:`/gallery/shapes_and_collections/hatch_style_reference` for swatches |
| 14 | +of the existing hatches. |
