echarts 自定义标注样式&自定义tooltip弹窗样式

1. 实现根据经纬度自定义标注图片样式

1. 设置 symbol 属性为 image://${require("@/assets/img/dataView/point.png")} 图片地址即可，注意前面跟 image:// 特有的写法
2. baseData 是经纬度数据，这里不贴了

let option = {
  tooltip: {
    .... //省略
  },
  geo: {
    .... //省略
  },
  series: [
    {
      type: "map",
      .... //省略
    },
    {
      type: "scatter",
      coordinateSystem: "geo",
      itemStyle: {
        color: "#f00",
      },
      tooltip: {
        trigger: "item",
        backgroundColor: "transparent",
        formatter: function (params) {
          return formatHtml(params.data);
        },
      },
      symbol: `image://${require("@/assets/img/dataView/point.png")}`,
      symbolSize: [48, 58],
      symbolOffset: [0, 0],
      z: 9999,
      data: this.baseData,
    },
  ],
};

2. 实现鼠标悬浮标注自定义弹窗样式内容

1. 结合上面代码，设置 tooltip 为自定义的一个函数 formatHtml ，内容如下，主要是自定义css样式即可

let formatHtml = ({ name, computilityData }) => {
  return `
        <div class="tooltip-chart">
        <div class="item">
            <span>基地名称</span>
            <span class="name">${name}</span>
        </div>
        <div class="item">
             <span>基地CPU服务器数量</span>
            <span>${computilityData?.baseCpuserverNumber || 0}</span>
        </div>
        <div class="item">
