   我做了一个折线图与漏斗图联动的逻辑，应该能解决你的问题。
   思路：点击折线图的时候获取到当前 `event` 像素坐标，然后通过 `convertFromPixel` 方法将其转化成数据坐标，然后就能知道相应数据了。
   
   关键代码如下：
   ```js
   // 折线图发射
       myChart.getZr().on('click', (params) => {
           let pointer = myChart.convertFromPixel({ seriesIndex: 0 }, [params.event.zrX, params.event.zrY]);
           let currentIndex = pointer[0];
           if (currentIndex !== undefined) {
               changeFunnel(currentIndex);
           }
       });
   ```
