title: Python seaborn catplot - How do I change the y-axis scale to percentage
body: <p>In the figure the y-axis labels are in decimals from (0 to 1) i.e (0.1, 0.2, 0.4 etc).  How can I convert this into a % format (10%, 20%, 40% etc).  Just 10, 20, 40 also will do.</p>
  
  <p>Thanks, John</p>
  
  <pre><code>g = sns.catplot(x="who", y="survived", col="class",
  ...                 data=titanic, saturation=.5,
  ...                 kind="bar", ci=None, aspect=.6)
  </code></pre>
