title: Two bar charts in matplotlib overlapping the wrong way
body: <p>I'm creating a bar plot with matplotlib in Python, and I'm having a bit of a problem with the overlapping bars:</p>
  
  <pre><code>import numpy as np
  import matplotlib.pyplot as plt
  
  a = range(1,10)
  b = range(4,13)
  ind = np.arange(len(a))
  width = 0.65
  
  fig = plt.figure()
  ax = fig.add_subplot(111)
  
  ax.bar(ind+width, a, width, color='#b0c4de')
  
  ax2 = ax.twinx()
  ax2.bar(ind+width+0.35, b, 0.45, color='#deb0b0')
  
  ax.set_xticks(ind+width+(width/2))
  ax.set_xticklabels(a)
  
  plt.tight_layout()
  </code></pre>

  <p>I want the blue bars to be in front, not the red ones. The only way I have managed to do so so far was to switch ax and ax2, but then the ylabels are going to be reversed as well, which I don't want. Isn't there a simple way to tell matplotlib to render ax2 before ax?</p>
  
  <p>In addition, the ylabels on the right are being cut off by plt.tight_layout(). Is there a way to avoid this while still using tight_layout?</p>
