title: Seaborn catplot transparency customizaton
body: <p>Seaborn comes with a relatively new <a href="https://seaborn.pydata.org/generated/seaborn.catplot.html" rel="nofollow noreferrer"><code>catplot</code></a> function. Is there a way to specify the transparency, conform the <code>alpha</code> parameter in for example <code>regplot</code>? (see this <a href="https://stackoverflow.com/questions/47200033/how-to-adjust-transparency-alpha-in-seaborn-pairplot">SO</a> question). </p>
  
  <p>The following does not work: </p>
  
  <pre><code>  sns.catplot(x = 'var1', y = 'var2', data=df, kind='box', plot_kws={ 'scatter_kws': {'alpha': 0.5}})
  </code></pre>
