matplotlib.patches.Annulus   classmatplotlib.patches.Annulus(xy, r, width, angle=0.0, **kwargs)[source]
 
Bases: matplotlib.patches.Patch An elliptical annulus.  Parameters 
 
xy(float, float)


xy coordinates of annulus centre.  
rfloat or (float, float)


The radius, or semi-axes:  If float: radius of the outer circle. If two floats: semi-major and -minor axes of outer ellipse.   
widthfloat


Width (thickness) of the annular ring. The width is measured inward from the outer ellipse so that for the inner ellipse the semi-axes are given by r - width. width must be less than or equal to the semi-minor axis.  
anglefloat, default: 0


Rotation angle in degrees (anti-clockwise from the positive x-axis). Ignored for circular annuli (i.e., if r is a scalar).  **kwargs
