title: Google Chart API: how can I change the format of dates on an axis?
body: <p>I have a google chart (set up using <a href="http://ankane.github.io/chartkick/" rel="noreferrer">chartkick</a> And I am trying to make the dates appear shorter on the chart. My Data set looks something like this:</p>
  
  <pre><code>{"03/01/13" : 3, "03/02/13" : 0, "03/03/13" : 10 }  //etc.
  </code></pre>
  
  <p>However, when I load up the chart the date is formatted like so:  Mar 1, 2013.
  How can I get the date to appear as I passed it, or in some other short format? The longer fields looked very cramped on the page I am using it on. </p>
