title: Flot donut chart disappears when labels are shown
body: <p>I have a created a simple donut chart with flot. However, if I use the default settings the labels are not displayed (even if I specify "show: true"). Only when I hide the legend, the labels are displayed but then the chart itself disappears. Am I missing something or is this a bug in the flot library?</p>
  
  <p>This is my code:</p>
  
  <pre><code>var data = [
    {label: "A", data: 373, color: "red"},
    {label: "B", data: 84, color: "blue"},
    {label: "C", data: 73, color: "green"}    
  ];
  
  $.plot("#chart", data, {
    series: {
      pie: {
        innerRadius: 0.75,
        show: true,
      }
    },
    label: {
      show: true,
    },
    legend: {
      show: false
    }
  });  
  </code></pre>
