title: Highchart not showing 0 data correctly for pie chart
body: <p>I have a highchart(pie chart) with multiple fields (here added only two). Which is giving me issue for 0 values.</p>
  
  <p>The conditions are as described below:</p>
  
  <p>If my first field is 100% the pie chart renders a line of 0% for the other field</p>
  
  <p>Refer to this fiddle : <a href="http://jsfiddle.net/rndmmuz6/4/" rel="nofollow noreferrer">http://jsfiddle.net/rndmmuz6/4/</a></p>
  
  <pre><code>data: [{
          name: 'Check1',
          y: 100
      },
      {
          name: 'Check2',
          y: 0
      }]
  </code></pre>
  
  <p>but if my second field is 100% then the pie chart does not render a 0% field for the first fields</p>
  
  <p>Refer to this fiddle : <a href="http://jsfiddle.net/rndmmuz6/3/" rel="nofollow noreferrer">http://jsfiddle.net/rndmmuz6/3/</a></p>
  
  <pre><code> data: [{
          name: 'Check1',
          y: 0
      },
      {
          name: 'Check2',
          y: 100
      }]
  </code></pre>
  
  <p>I want the line to always appear.</p>
