  <p>And I make the above plot using <code>plotnine</code>. What I would like to do, is 2 things:</p>
  
  <p>1) Move the labels a little bit so that they do not fall on the line</p>
  
  <p>2) Add in the line also the 25th &amp; 75th quantiles</p>
  
  <p>Any ideas how to do that using <code>plotnine</code> ?</p>
