title: Highcharts tooltip arrow position
body: <p>I'm trying to modify the Highcharts tooltip for a stacked column graph so that the little arrow on the tooltip points to the middle of the bar. I know I can use the <code>positioner</code> callback to change the position of the tooltip but it seems like the arrow always points to the top of the bar no matter what its position is. See my fiddle for what I mean: <a href="http://jsfiddle.net/4dy46vfx/1/" rel="nofollow noreferrer">http://jsfiddle.net/4dy46vfx/1/</a>.</p>
  
  <p>Below is a crude screenshot of what I'm after:</p>

  <p>Is there any way to change the position of the tooltip arrow?</p>
