echarts实现贵州地图

1. 添加标签

<div id="elementId" class="guizhou-map"
style="width: 600px; height: 400px"
></div>

import * as echarts from "echarts";
import mapGeoJson from "./guizhou.json"; //注册地图的数据
 
    initMap() {
      // 构造 tooltip 数据
      let outData = {}
      mapGeoJson.features.forEach(item=>{
        outData[item.properties.name] =  Math.floor(Math.random()*1000+1);
      })
      let option = {
        // backgroundColor: "#0E0F35",
        // backgroundColor: "#0E0F35",
        tooltip: {
          show: true,
          formatter: function (params) {
              return (
                "  " +
                params.name +
                "   " +
                outData[params.name] +
                "亿元  "
              );
          },
        },
        series: [
          {
            name: "乡镇地图",
            type: "map",
            map: "townMap", //使用 registerMap 注册的地图名称
            data: [],
            label: {
              normal: {
                show: true,
              },
              emphasis: {
                show: true,
              },
            },
          },
        ],
      };
      let myChart = echarts.init(document.getElementById("elementId"));
      echarts.registerMap("townMap", mapGeoJson);
      option && myChart.setOption(option);
    },
