   为了方便我们能够复现和修复 bug，请遵从下面的规范描述您的问题。

   ### One-line summary [问题简述]
   JSON数据
   {"pointType":"['A','B','C','D','E','F']","data":"[{name:'A',value:47},{name:'B',value:12},{name:'C',value:1},{name:'D',value:117},{name:'E',value:2},{name:'F',value:10}]"}
   
   > $.getJSON('获取JSON地址').done(function (data) {
     option = {
       legend: {
         data: data.pointType
       },
       series : [
         {
           data: data.data
         }
       ]
       };
       myChart.setOption(option);
   }
   
   最后饼图把JSON数据中value的值单字分开，如47，饼图显示就是 4一块 7一块
   
   ### Version & Environment [版本及环境]
   + ECharts version [ECharts 版本]:4.0.4
   + Browser version [浏览器类型和版本]:Chrome 55
   + OS Version [操作系统类型和版本]:
   
   
   
   
   
   ### Expected behaviour [期望结果]
   正常显示饼图
   如果赋值
   
   >  var tmp = "[{name:'A',value:47},{name:'B',value:12},{name:'C',value:1},{name:'D',value:117},{name:'E',value:2},{name:'F',value:10}]"; 
   
   可以正常显示
   
   
   
   ### ECharts option [ECharts配置项]
   <!-- Copy and paste your 'echarts option' here. -->
   <!-- [下方贴你的option，注意不要删掉下方 ```javascript 和 尾部的 ``` 字样。最好是我们能够直接运行的 option。如何得到能运行的 option 参见上方的 guidelines for contributing] -->
   ```javascript
   option = {
   title : {
       text: optText,
       subtext: '统计',
       x:'center'
   },
   tooltip : {
       trigger: 'item',
       formatter: "{a} <br/>{b} : {c} ({d}%)"
   },
   legend: {
       orient: 'vertical',
       left: 'right',
       data: []
   },
   series : [
       {
           name: '数量',
           type: 'pie',
           radius : '55%',
           center: ['50%', '60%'],
           data:[],
           itemStyle: {
               emphasis: {
                   shadowBlur: 10,
                   shadowOffsetX: 0,
                   shadowColor: 'rgba(0, 0, 0, 0.5)'
               }
           }
       }
   ]
   }
   
   ```
