matplotlib.patches.Polygon

class matplotlib.patches.Polygon(xy, closed=True, **kwargs)

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 kwargs 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	float or None
animated	bool
antialiased or aa	bool or None
capstyle	[‘butt’ | ‘round’ | ‘projecting’]
clip_box	a Bbox instance
clip_on	bool
clip_path	[(Path, Transform) | Patch | None]
color	matplotlib color spec
contains	a callable function
edgecolor or ec	mpl color spec, None, ‘none’, or ‘auto’
facecolor or fc	mpl color spec, or None for default, or ‘none’ for no color
figure	a Figure instance
fill	bool
gid	an id string
hatch	[‘/’ | ‘' | ‘|’ | ‘-‘ | ‘+’ | ‘x’ | ‘o’ | ‘O’ | ‘.’ | ‘*’]
joinstyle	[‘miter’ | ‘round’ | ‘bevel’]
label	object
linestyle or ls	[‘solid’ | ‘dashed’, ‘dashdot’, ‘dotted’ | (offset, on-off-dash-seq) | '-' | '--' | '-.' | ':' | 'None' | ' ' | '']
linewidth or lw	float or None for default
path_effects	AbstractPathEffect
picker	[None | bool | float | callable]
rasterized	bool or None
sketch_params	(scale: float, length: float, randomness: float)
snap	bool or None
transform	Transform
url	a url string
visible	bool
zorder	float

For additional kwargs

get_closed()

Returns if the polygon is closed

Returns:

closed : bool

If the path is closed

get_path()

Get the path of the polygon

Returns:

path : Path

The Path object for the polygon

get_xy()

Get the vertices of the path

Returns:

vertices : numpy array

The coordinates of the vertices as a Nx2 ndarray.

set_closed(closed)

Set if the polygon is closed

Parameters:

closed : bool

True if the polygon is closed

set_xy(xy)

Set the vertices of the polygon

Parameters:

xy : numpy array or iterable of pairs

The coordinates of the vertices as a Nx2 ndarray or iterable of pairs.

xy

Set/get the vertices of the polygon. This property is provided for backward compatibility with matplotlib 0.91.x only. New code should use get_xy() and set_xy() instead.
