title: Highcharts - change column stacking on click
body: <p>I have a lovely Highcharts plot with stacked columns. I'd like a button which can toggle whether the stacking is 'normal' or 'percent'.</p>
  
  <p>I'm trying the following (which doesn't work):</p>
  
  <pre><code>  $('#button').click(function () {
          var chart = $('#container').highcharts();
          chart.options.plotOptions.column.stacking = 'percent';
          chart.redraw();
    });
  </code></pre>
  
  <p>Fiddle here: <a href="http://jsfiddle.net/CRKcj/2/" rel="noreferrer">http://jsfiddle.net/CRKcj/2/</a></p>
  
  <p>Any help would be much appreciated!</p>
