title: plotting dates backwards matplotlib / pandas
body: <p>I would like to plot a graph with the most recent dates on the left instead of the right of the x-axis. </p>
  
  <p>Is there a way to do this in pandas and matplotlib and still get the date axis?</p>

  <p>shows how to do this for the y-axis using invert_yaxis(). However, this is not available for xaxis.</p>
