title: How to increase the thickness of error line in a matplotlib bar chart?
body: <p>Please refer the minimum working example <a href="http://matplotlib.org/examples/api/barchart_demo.html" rel="noreferrer">here</a>.</p>
  
  <p>The bar chart is plotted as shown below but I can't find a way to increase the thickness of the error lines. The <code>elinewidth</code> option is not available in <code>ax.bar</code></p>
  
  <pre><code>&gt; rects1 = ax.bar(..., elinewidth=3)
  
  AttributeError: Unknown property elinewidth
  </code></pre>

  <p>The following links require the use of <code>ax.errorbar()</code> </p>

  </ul>
  
  <p>But is there an option that can be supplied directly to <code>ax.bar()</code>?</p>
