title: Enable or disable data labels shown in pie charts in Highcharts on click of a button
body: <p>I have a dynamic pie chart. On the click of a button the data labels shown when 
  <code>dataLables</code> is true to show data points and when it is false it should be hidden.</p>
  
  <pre><code>plotOptions: {
      pie: {
          allowPointSelect: false,
          cursor: 'pointer',
          dataLabels: {
              enabled: false
          }
      }
  }
  </code></pre>
