title: How to create one corner plot with two sets of data
body: <p>I am plotting a simple corner plot in python using corner.py:</p>
  
  <pre><code>corner(my_data)
  </code></pre>
  
  <p>to produce something like:</p>
  
  <p><a href="https://i.stack.imgur.com/cvW3K.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/cvW3K.png" alt="enter image description here"></a></p>
  
  <p>I want to create a corner plot that superimposes <code>my_data</code> and <code>my_other_data</code> on one corner plot. Is this possible? Or would I have to make my own version of a corner plot rather than using corner.py?</p>
  
  <p>Thanks.</p>
