title: AttributeError: 'ErrorbarContainer' object has no attribute 'set_ylim'
body: <p>I am plotting the results of some experiments with error bars. I'd like to be able to set the y limit in the case of results with extreme outliers that aren't interesting. This code:</p>
  
  <pre><code>axes = plt.errorbar(feature_data[feature_data.num_unique[feature_of_interest] &gt; 1].index, chi_square_y, yerr=chi_square_y_error, fmt = 'o')
  axes.set_ylim([-.2, .2])
  plt.plot((min(feature_data[feature_data.num_unique[feature_of_interest] &gt; 1].index), max(feature_data[feature_data.num_unique[feature_of_interest] &gt; 1].index)), (0, 0), 'r--', linewidth = 2)
  </code></pre>
  
  <p>produces this error:</p>

  <p>How can I set the y limits?</p>
  
  <p>Thanks!</p>
