title: How can I plot the standard error on the error bars in seaborn's barplot?
body: <p>I have a nice figure that is plotted with generic code as follows:</p>
  
  <pre><code>import seaborn as sns
  sns.barplot(data=df, x='X', y='y', hue='HUE', capsize=.1)
  </code></pre>
  
  <p>The errorbars by default display the 95% confidence interval (I think). Is there a way I can easily change them to standard error?</p>
