matplotlib.patches.Circle

class matplotlib.patches.Circle(xy, radius=5, **kwargs)

A circle patch.

Create true circle at center xy = (x, y) with given radius. Unlike CirclePolygon which is a polygonal approximation, this uses Bézier splines and is much closer to a scale-free circle.

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	[True | False] or None for default
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

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
