title: X-axis ticks (label) are not displaying properly as dates
body: <p>I have a graph like in this link: <a href="http://jsfiddle.net/bqE7H/" rel="nofollow">http://jsfiddle.net/bqE7H/</a><br>
  I want to display the X-axis labels as dates like nov 1, nov 7, nov 13 in place of
  1.0, 7.0, 13.0. I have tried using <code>dateAxesrenderer</code> but it is not working. What am I doing wrong?</p>
