Hatch demo#
Hatches can be added to most polygons in Matplotlib, including bar
,
fill_between
, contourf
, and children of 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 Contourf Hatching for
an example using contourf
, and
Hatch style reference for swatches
of the existing hatches.
