title: Removing right edge from pyplot histogram
body: <p>I refer to this <a href="https://matplotlib.org/examples/statistics/histogram_demo_cumulative.html" rel="noreferrer">example</a> from the Matplotlib site. To the right of the blue "Empirical" curve, there is a vertical blue line, which is the right edge of the rightmost bar.</p>
  
  <p>How can I remove this vertical blue line, without changing the x-axis limits?</p>
