title: Count number of times a date occurs and make a graph out of it
body: <p>I have a list of dates, each date in it can occur more than once. I want to count the number of times each date occurs (histogram) and display it in a graph (with the Y axis being the number of times the date occurs and the X axis being the date itself)?</p>
  
  <p>Sample list:</p>
  
  <pre><code>19/05/2012
  19/05/2012
  19/05/2012
  17/05/2012
  17/05/2012
  16/05/2012
  16/05/2012
  16/05/2012
  16/05/2012
  15/05/2012
  15/05/2012
  15/05/2012
  15/05/2012
  12/05/2012
  12/05/2012
  12/05/2012
  7/05/2012
  </code></pre>
  
  <p>I clicked every menu option over the past few years and never did I find anything specific to this. Would this be a case for using PivotTables somehow?</p>
