title: Seaborn RegPlot Partially See Through (alpha)
body: <p>When using seaborn barplot I can specify an alpha for which it makes the bars semi-translucent.  However, when I try this with Seaborn regplot I get an error saying this is an unexpected argument.</p>
  
  <p>I read the documentation online and didn't find much, could someone point me in the right direction...</p>
