}];
percent来自原始数据personalityChart,str来自echarts渲染后数据

在tooltip格式化处理系列名,画图字段为value,效果图:

问题二:echarts-series中label的backgroundColor无效
一开始我是像上面那样写的 发现图片出不来,不能用本地的图片

所以我把图片放到服务器上通过http去请求获取,但是发现图片长宽不是我设置的长宽

查看配置文档发现

如果不定义 rich 属性,则不能指定 width 和 height。

官网上面的某个例子,也可以拿图片当背景,满足
const weatherIcons = {
  Sunny: ROOT_PATH + '/data/asset/img/weather/sunny_128.png',
  Cloudy: ROOT_PATH + '/data/asset/img/weather/cloudy_128.png',
  Showers: ROOT_PATH + '/data/asset/img/weather/showers_128.png'
