第一步：先引入所需的第三方模块

import echarts from "echarts"; // 引入所需要的echarts模块
import "echarts/map/js/province/shanxi"; // 引入省份的js文件
import "echarts/map/json/province/shanxi.json"; // 引入省份的json文件

第二步：开始绘制

// 基于准备好的dom，初始化echarts实例
      var myChart = echarts.init(document.getElementById("left2"));
      var option = {
        visualMap: {
          show: false,
          min: 0,
          max: 100,
          left: "left",
          top: "bottom",
          text: ["高", "低"], // 文本，默认为数值文本
          calculable: true,
          inRange: {
            color: ["yellow", "lightskyblue", "orangered"],
          },
        },
        series: [
          {
            layoutCenter: ['30%', '30%'],
            type: "map",
            mapType: "山西",
            roam: true,
            label: {
              normal: {
                show: true,
                textStyle: {
                  fontSize: 10,
                  fontFamily: "楷体",
                },
              },
              emphasis: {
                  color: "#fff",
            },
            itemStyle: {
                borderColor: "#389BB7",
                areaColor: "#fff",
                areaColor: "#389BB7",
                borderWidth: 0,
            animation: false,// 数据
            data: [
              {
                name: "大同市",
                value: 88,
                name: "朔州市",
                value: 96,
                name: "忻州市",
                value: 98,
                name: "吕梁市",
                value: 80,
                name: "太原市",
                name: "晋中市",
                value: 79,
                name: "阳泉市",
                value: 77,
                name: "临汾市",
                value: 33,
                name: "长治市",
                value: 69,
                name: "运城市",
                value: 66,
                name: "晋城市",
                value: 22,
            ],
        ],
      };
      myChart.setOption(option);

最后结果：

补充：vue2.x结合echarts2实现显示具体省份热力图

最近研究了一下VUE2.X结合ehcarts实现热力图，先看下最终：

效果话不多说，直接上代码：

　　　说一下：china.js或各个省份对应的js文件在node包里面就有，是比较全面的。有的说这里没有用到VUE啊，对的，在这里没引入（那是我的项目额！），不过不用担心，因为vue里面直接引入是完全兼容的啦！　

　　代码看似很简单，但是里面的坑很多。因为我是在项目中直接使用的，本来想着有node包，就没有引入china.js或者具体省份对应的js文件，造成一些问题。第二个就是关于坐标轴、网格的设置，有些设置是相关联的，要注意。第三个就是在网上自行找到新疆省份下各个区锁对应的经纬度（这个渠道很多，就不多啰嗦了）。第四个就是在visualMap中的设置，这个我也是费了很大力气才实现的，有兴趣的朋友可以自己先试试，看看怎么玩，希望大家相互学习，共同进步。最后就是该项目地址我已经放到git了，欢迎大家mark并且star!

注意是：start!!!多谢多谢git仓库地址:https://github.com/WangHao1221/vueWithEcharts.git
