title: Highcharts 3.0 combination chart not fully rendering pie (donut) chart
body: <p>I have a Highcharts 3.0 chart that shows both a column chart and a pie (donut) chart. This combo chart was rendering fine with the previous version of Highcharts.</p>
  
  <p>Since upgrading the donut chart only renders to the highest y axis line and does not render above that line. The pie (donut) chart used to render completely with the top half of the pie (donut) chart being to the right of the chart title.</p>
  
  <p>Any ideas?</p>

  <p>I have added a jsfiddle with a small modification to the Highcharts provided combination chart (<a href="http://www.highcharts.com/demo/combo" rel="nofollow noreferrer">http://www.highcharts.com/demo/combo</a>) to show the issue.</p>
  
  <p>The only line I changed is where to center the pie chart.</p>
  
  <pre><code>center: [300, 1],
  </code></pre>
