matplotlib.patches.Ellipse

class matplotlib.patches.Ellipse(xy, width, height, angle=0.0, **kwargs) [source]

A scale-free ellipse.

xy: center of ellipse
width: total length (diameter) of horizontal axis
height: total length (diameter) of vertical axis
angle: rotation in degrees (anti-clockwise)

Valid kwargs are:

`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

`transform`	`Transform`
`url`	a url string
`visible`	bool
`zorder`	float

get_patch_transform() [source]

Return the Transform instance which takes patch coordinates to data coordinates.

For example, one may define a patch of a circle which represents a radius of 5 by providing coordinates for a unit circle, and a transform which scales the coordinates (the patch coordinate) by 5.
