matplotlib.patches.Arc

class matplotlib.patches.Arc(xy, width, height, angle=0.0, theta1=0.0, theta2=360.0, **kwargs)

An elliptical arc. Because it performs various optimizations, it can not be filled.

The arc must be used in an Axes instance—it can not be added directly to a Figure—because it is optimized to only render the segments that are inside the axes bounding box with high resolution.

The following args are supported:

xy

center of ellipse

width

length of horizontal axis

height

length of vertical axis

angle

rotation in degrees (anti-clockwise)

theta1

starting angle of the arc in degrees

theta2

ending angle of the arc in degrees

If theta1 and theta2 are not provided, the arc will form a complete ellipse.
