echarts绘制省份地图并添加自定义标注

效果图

在main.js中引入地图

import echarts from 'echarts'
Vue.prototype.$echarts = echarts;

省份是动态引入的,在.vue文件中

html部分

<div id="province_map_box">
   <div id=province_map"></div>
</div>

css部分

<style lang="scss" scoped>
  #province_map_box {
    height: 500px;
    position: relative;
  }
  #province_map_box #province_map{
    height: 100%;
  }
  #province_map_box .province_map_logo{
    position: absolute;
    top: 0;
    left: 0;
    width:45px;
  }
</style>
<style lang="scss">
  #province_map.tooltip_style{
    line-height:1.7;
    overflow: hidden;
  }
  #province_map.tooltip_left{
    float: left;
  }
  #province_map.tooltip_right{
    float: right;
  }
</style>

script部分

data () {
    return {
        options: {
            geo: {
              map: "city",
              scaleLimit: {
                min: 1,
                max: 2
              },

                }
              },
              itemStyle: {

                   borderColor: "rgba(0, 0, 0, 0.2)",
                   areaColor: "#3b9cff",//设置地图区域背景色
                },
                emphasis: {
                  areaColor: "#3b9cff",

                  shadowOffsetY: 0
                }
              }
            },
            series: [
              {

                map: 'province',
                data:[]
              },
              {
                name: '企业分布', //红色标注
                type: 'custom',
                coordinateSystem: 'geo',
                clickable:true,
                data:[]
              }
            ]
        }   
    },
    cityJson: {
      features: []
    }
},
created(){
    this.city = this.$route.query.city
},
mounted() {
  this.$nextTick(()=>{
     this.initEchartMap()
   })
},
methods:{
    //初始化中国地图
    initEchartMap() {
      let mapDiv = document.getElementById('japan_map')
      let myChart = this.$echarts.init(mapDiv)
      let city = this.city
      //动态引入省份json文件
      this.cityJson = require(`echarts/map/json/province/${city}.json`)
      this.$echarts.registerMap('city', this.cityJson, {})
      this.setEchartOption()
      myChart.setOption(this.options)
      //可为自定义图标添加点击事件
      myChart.on('click', {element: 'aaa'}, (params) => {
        // todo: 当 name 为 'aaa' 的图形元素被点击时,此回调被触发。
      });
    },
    //修改echart配制
    setEchartOption(){
        //红色标注点的坐标
        let markList = [
          { name: '五常', value: [123.523565,52.920114] },
          { name: '中治', value: [126.319954,46.400728] },
          { name: '中顺', value: [133.310927,47.271857] },
          { name: '常也', value: [129.631468,45.65747] },
          { name: '可谭', value: [130.551333,47.321922] },
          { name: '顺允', value: [125.436884,48.460261] },
        ]
        this.options.series[1].data = markList
        if(markList.length>0){
            this.options.series[1].renderItem = function(params,api){
            return {
                type: 'image',
                name: 'aaa',
                style: {
                  image: require("@/assets/img/icon_mark.png"), //标注点图标
                  width: 14,
                  height: 18,
                  x: api.coord([markList[params.dataIndex].value[0], markList[params.dataIndex].value[1]])[0],
                  y: api.coord([markList[params.dataIndex].value[0], markList[params.dataIndex].value[1]])[1]
                }
            }
        }
      }
    }
}

注: echarts v4.2.1版本安装后会有地图json文件
