title: Matplotlib bar graph not drawing borders/edges
body: <p>I have this code for my bar graph.</p>
  
  <pre><code>ax1 = plt.subplot2grid((1,1),(0,0))
  ax1.bar(edges2, Nnorm, width=0.02, edgecolor='green', linewidth=20)
  </code></pre>
  
  <p>I thought that should make my bar graph have green edges.  But it does not.  It makes one bar on the far left green.  What am I doing wrong?  Facecolor works.  </p>
