title: Highcharts update pointRange, pointWidth after initial render
body: <p>Is it possible to update the pointRange on a column type <a href="http://api.highcharts.com/highcharts" rel="nofollow">HighCharts</a> chart, which has already been rendered?</p>
  
  <p>Seems like it would be a common request, but I can't get it to work..</p>
  
  <pre><code>chart.options.plotOptions.column.pointRange
  chart.options.plotOptions.column.pointWidth
  </code></pre>
