 [Matplotlib-users] Problem with Arcs From: Carlos Guâno Grohmann - 2009-05-18 17:14:35 ```Hello all I'm having some troubles with Arcs in MPL. Using the following code: circ = Arc( (0,0), width=2, height=2, angle=0.0, theta1=0.0, theta2=360.0, ec=None, fc=None) axes.add_patch(circ) gives: Traceback (most recent call last): File "pystereo22.py", line 524, in onPlotRose circ = Arc( (0,0), width=2, height=2, angle=0.0, theta1=0.0, theta2=360.0, ec=None, fc='none') File "/usr/lib/python2.5/site-packages/matplotlib/patches.py", line 1043, in __init__ fill = kwargs.pop('fill') KeyError: 'fill' It's working fine with Circle or Ellipse.

 Re: [Matplotlib-users] Problem with Arcs From: Michael Droettboom - 2009-05-18 17:28:47 ```Arcs exist as an optimization to render really large circles and ellipses with high accuracy. An elliptical arc. Because it performs various optimizations, it can not be filled. If you want to draw a filled, yet partial, circle, I believe you want to use Wedge.
