title: highcharts stacked area
body: <p>So I think I may have encountered a Highcharts bug in terms of stacked area:</p>
  
  <p><a href="http://jsfiddle.net/dRL6t/2/" rel="nofollow">JSFiddle Highcharts Example</a></p>
  
  <p>In this example, the "Social" has a start point before the "Online Video" and seems to render the points of the stacked areas erratically. If you were to deselect the charts from left to right, and then select them from right to left, the charts will render correctly. Has anyone else encountered this?</p>
