title: Highcharts: How do I set dynamic data to the drilldown pie chart?
body: <p>I am able to set data to the main pie chart using </p>
  
  <pre><code>var data = [1,2,3,4,5]; //value of data will be returned through an AJAX call
  chart1.series[0].setData(data);
  </code></pre>
  
  <p>Similarly, how do I set the drilldown data dynamically?</p>
  
  <p>I tried with </p>
  
  <pre><code>chart1.drilldown[0].data = '[1,2,3]';
  </code></pre>
  
  <p>but it did not work.</p>
  
  <p>I am using <code>RESTful</code> services to expose data.</p>
