Btista commented on issue #4125: 如何在legend中显示value值？ URL: https://github.com/apache/incubator-echarts/issues/4125#issuecomment-421220755 不过我找了一种新思路，分享给需要的人： 因为问题的关键在于formatter回调函数里取不到value， 但是echarts提供的api里可以通过echartsInstance.getOption 得到option配置，则可以顺着拿到echartsInstance.getOption().series[0].data , 完了再通过这个回调函数里能取到的name来遍历echartsInstance.getOption().series[0].data最终取到value。 虽然比较绕，但是也能最后拿到哈
