   ```java script
   option = {
       title: {
           text: 'Awesome Chart'
       },
       xAxis: {
           data: ['Sun', 'Mon', 'Tue', 'Wed', 'Thu', 'Fri', 'Sat']
       },
       yAxis: {},
       series: [{
           type: 'line',
           data:[220, 182, 191, 234, 290, 330, 310],
           // 文档中说symbol可以是Function，但我观察代码，发现并没有实现此功能。
           symbol: function (value) {
               if (value > 200) {
                   return 'circle'
               }
               return 'rect'
           }
       }]
   };
   ```
