title: How to skip empty dates (weekends) in a financial Matplotlib Python graph?
body: <pre><code>ax.plot_date((dates, dates), (highs, lows), '-')
  </code></pre>
  
  <p>I'm currently using this command to plot financial highs and lows using <a href="http://en.wikipedia.org/wiki/Matplotlib" rel="noreferrer">Matplotlib</a>. It works great, but how do I remove the blank spaces in the x-axis left by days without market data, such as weekends and holidays?</p>
  
  <p>I have lists of dates, highs, lows, closes and opens. I can't find any examples of creating a graph with an x-axis that show dates but doesn't enforce a constant scale. </p>
