title: Highcharts - verticalAlign on dataLabels not working on line graph
body: <p>I have a Highcharts line graph and I'm considering adding dataLabels to each point. According to the <a href="http://api.highcharts.com/highcharts#plotOptions.line.dataLabels.verticalAlign" rel="nofollow">API documentation</a>, you can change the vertical placement via verticalAlign, but it doesn't seem to work.</p>
  
  <p>I tried editing the <a href="http://jsfiddle.net/gh/get/jquery/1.7.2/highslide-software/highcharts.com/tree/master/samples/highcharts/demo/line-labels/" rel="nofollow">jsfiddle of the basic line</a> graph to include this:</p>
  
  <pre><code> plotOptions: {
              line: {
                  dataLabels: {
                      enabled: true,
                      verticalAlign: 'bottom'
                  },
                  enableMouseTracking: false
              }
          },
  </code></pre>
  
  <p>While the dataLabels are enabled, the vertical position doesn't change regardless of what I put for the verticalAlign value. Anyone had this issue with line graphs?</p>
