matplotlib.patches.Polygon

classmatplotlib.patches.Polygon(xy, closed=True, **kwargs)[source]

Bases: matplotlib.patches.Patch

A general polygon patch.

xy is a numpy array with shape Nx2.

If closed is True, the polygon will be closed so the starting and ending points are the same.

Valid keyword arguments are:

Property	Description
agg_filter	a filter function, which takes a (m, n, 3) float array and a dpi value, and returns a (m, n, 3) array
alpha	unknown
animated	bool
antialiased or aa	bool or None
capstyle	CapStyle or {'butt', 'projecting', 'round'}
clip_box	Bbox
clip_on	bool
clip_path	Patch or (Path, Transform) or None
color	color
edgecolor or ec	color or None
facecolor or fc	color or None
figure	Figure
fill	bool
gid	str
hatch	{'/', '\', '|', '-', '+', 'x', 'o', 'O', '.', '*'}
in_layout	bool
joinstyle	JoinStyle or {'miter', 'round', 'bevel'}
label	object
linestyle or ls	{'-', '--', '-.', ':', '', (offset, on-off-seq), ...}
linewidth or lw	float or None
path_effects	AbstractPathEffect
picker	None or bool or float or callable
rasterized	bool
sketch_params	(scale: float, length: float, randomness: float)
snap	bool or None
transform	Transform
url	str
visible	bool
zorder	float

get_closed()[source]

Return whether the polygon is closed.

get_path()[source]

Get the Path of the polygon.

get_xy()[source]

Get the vertices of the path.

Returns

(N, 2) numpy array

The coordinates of the vertices.

set_closed(closed)[source]

Set whether the polygon is closed.

Parameters

closedbool

True if the polygon is closed

set_xy(xy)[source]

Set the vertices of the polygon.

Parameters

xy(N, 2) array-like

The coordinates of the vertices.

Notes

Unlike Path, we do not ignore the last input vertex. If the polygon is meant to be closed, and the last point of the polygon is not equal to the first, we assume that the user has not explicitly passed a CLOSEPOLY vertex, and add it ourselves.

propertyxy

The vertices of the path as (N, 2) numpy array.
