title: How to show the y-axis of seaborn displot as percentage
body: <p>I'm using seaborn.displot to display a distribution of scores for a group of participants.</p>
  <p>Is it possible to have the y axis show an actual percentage (example below)?</p>
  <p>This is required by the audience for the data.
  Currently it is done in excel but It would be more useful in python.</p>
  <pre class="lang-py prettyprint-override"><code>import seaborn as sns
  
  data = sns.load_dataset('titanic')
  
  p = sns.displot(data=data, x='age', hue='sex', height=4, kind='kde')
  </code></pre>
