   或许可以尝试这种方式？
   
   ```js
   var selectedData = [];
   
   myChart.setOption({
       // ...
       series: [{
           id: 'all'
           data: [ ... ]
       }, {
           id: 'selected',
           data: selectedData
           z: 1000
       }]
   };
   
   myChart.on('click', function (params) {
       if (selectedData.indexOf(params.dataIndex) < 0) {
           selectedData.push(params.value);
       })
       myChart.setOption({
           series: {
               id: 'selected',
               data: selectedData
           }
       })
   })
   ```
