title: Matplotlib: Change linewidth on all subplots
body: <p>I'm plotting a grid of subplots (6x2) with matplotlib (version 1.3.1) and Python 2.7.  I set up my figure and plot things in the subplots like this:</p>
  
  <pre><code>fig, axes = plt.subplots(ncols=6, nrows=2, 
                           sharex=True, sharey=True, figsize=(30,5))
  
  axes[0,0].plot(x, y)
  axes[1,5].plot(z, a)
  </code></pre>
  
  <p>etc.  </p>
  
  <p>My question is this:  is there a way to change the line properties on all of these plots at once?  I could manually specify <code>axes[0,0].plot(x,y,'k',linewidth=2.0)</code> on each of the axes, but I thought there must be a way to do it for all 12 plots at once.</p>
  
  <p>Cheers.</p>
