echarts繪制省份地圖并添加自定義標注

效果圖

在main.js中引入地圖

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

省份是動態(tài)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

注： echarts v4.2.1版本安裝后會有地圖json文件

echarts添加地圖標點（筆記）
