使用jQuery插件Flot,繪製餅圖

1、使用前，引用需引用：

<script src="jquery.flot.js"></script>
<script src="jquery.flot.pie.js"></script>

2、代碼如下：

<script type="text/javascript" >
 $(window).load(function(){
  drawPie(); 
 });
 
 var drawPie = function(){
  $(function() {
  
   var testData =  [88, 125, 200]; 
   var data = [{
    label : "data1",
    data : testData[0]
   }, 

  {
    label : "data2",
    data : testData[1]

   {
    label : "data3",
    data : testData[2]-testData[0]

   }];
   
   $.plot($("#pieDiv"), data, {
    series : {
     pie : {
      show : true,
      //innerRadius: 0.5,
      radius: 0.65,
      label: {
                      show: true,
                      radius: 1/3,
                      formatter: function(label, series){
                          return '<div style="font-size:5pt;text-

align:center;padding:2px;color:black;">'
                          +Math.round(series.percent)+'%</div>';
                      }
                  }
     }
    },
    colors: ["#FF0000", "#00FF00","#0000FF"],
    grid: {
              hoverable: true,
          },
          legend: {
              show: true,
              labelFormatter:function labelFormatter(label, series) {
                  return '<div style="font-size:8pt; text-align:center; padding:2px; 

color:'+series.color+';">' 
                  +label+'</div>';
              }
          }
   });
  });
  
 }
</script>
