title: Highcharts - add a second needle to a VU Meter with a different colour
body: <p>Is there a way to add a second needle of a different colour to a VU Meter ('gauge') style chart in Highcharts?  I know that you can change the colour of the needle per chart using plotOptions:gauge:dial e.g.</p>
  
  <pre><code>plotOptions: {
          gauge: {
              dial: {
                  radius: '100%',
                  backgroundColor : 'grey'
              }
          }
      }
  </code></pre>
  
  <p>and I have tried to overlay a second pane and specify individual plotOptions (as per this fiddle (<a href="http://jsfiddle.net/jdalton/xfV5k/8/" rel="nofollow">http://jsfiddle.net/jdalton/xfV5k/8/</a>) but without any success</p>
