Can't plot ellipse in python without fillcolor
<p>I really can't get this and I need to superimpose an ellipse onto an image. The problem is plotting the ellipse with the matplotlib.patches, but ending up with either a white graph or a filled ellipse. The code is very primitive and I'm not sure what to do, since I've never worked with this part of the matplotlib library.</p>

<pre><code>import matplotlib.pyplot as plt
import numpy.random as rnd
from matplotlib.patches import Ellipse


ells = [Ellipse(xy=[0,0], width=30, height=10, angle=0,edgecolor='b', lw=4)]

fig = plt.figure(0)
ax = fig.add_subplot(111, aspect='equal')
for e in ells:
    ax.add_artist(e)
    e.set_alpha(1)
    e.set_facecolor(none) #obvious mistake, but no idea what to do

ax.set_xlim(-100, 100)
ax.set_ylim(-100, 100)

plt.show()
</code></pre>

<p>I tried looking up the matplotlib.patches page, but there is no clear info on how to plot an ellipse, just the function in use.</p>

<p>Would greatly appreciate some help.</p>

<p>Thank you for your time.</p>
