title: what is matplotlib's retina display mode?
body: <p>What is retina display mode in matplotlib? I searched a lot and only thing I get is how to use it in jupyter notebook. How is it different? Does it have something to do with apple's retina display?</p>
  
  <p>EDIT: </p>
  
  <p>In jupyter notebook, this is how the code is written:</p>
  
  <pre><code>import matplotlib.pyplot as plt
  %matplotlib inline
  %config InlineBackend.figure_format='retina'
  </code></pre>
  
  <p>My doubt is what does this retina mode does? How is it different from other modes?</p>
