   拿柱图自己做一个图例是不是可以？做了个简易的示例：

   ```myChart.on('click', {
       seriesName: 'myLegend'
   }, function(params) {
       console.log(123);
       console.log(params);
   
       if (params.color === '#CCC') {
           myChart.dispatchAction({
               type: 'legendSelect',
               // 图例名称
               name: params.name
           });
           option.series[params.seriesIndex].data[params.dataIndex].itemStyle.color = colorList[params.dataIndex];
           myChart.setOption(option);
   
       } else {
           myChart.dispatchAction({
               type: 'legendUnSelect',
               // 图例名称
               name: params.name
           });
           option.series[params.seriesIndex].data[params.dataIndex].itemStyle.color = '#CCC';
           myChart.setOption(option);
   
       }
   });```
