title: Dual axis using percentage and absolute value to same serie in Highcharts
body: <p>I need use a percentage and absolute value of the axis Y from the one serie.</p>
  
  <p>There is some example in highchart <a href="http://www.highcharts.com/demo/combo-multi-axes" rel="nofollow">http://www.highcharts.com/demo/combo-multi-axes</a> but it's using two different series. I need, for example, value in axis Y until 1000 and in the other axis Y show the percentage to the item serie.</p>
