  <p>The dynamics I don't need. I do need the foreground curves obscuring the background curves.</p>
  
  <p>These are used in pulsar astronomy.</p>
  
  <p>I've experimented with</p>
  
  <p>plt.fill()  and</p>
  
  <p>plt.fill_between()</p>
  
  <p>With no success. Is there an example somewhere in python someone knows about?</p>
