title: Required format for month-day-year plot in matplotlib
body: <p>I have a .csv file with one column containing the date using backslashes '/' to separate the month, day and year in one column.  The following three columns contain a mean financial value, an upper financial value and a lower financial value.  The data format look like the following example;</p>
  
  <pre><code>3/2/14  18338.98    18734.07    17943.88
  3/3/14  18280.09    18675.2     17884.99
  3/4/14  18220.26    18614.53    17825.98
  3/5/14  18160.29    18551.71    17768.87
  </code></pre>
  
  <p>How can I get python to read in the date column and recognize it as a date in the format of month, day, year for eventual plotting with matlibplot? </p>
