@vue+echarts实现中国地图流动效果
#话不多说看效果图
操作步骤：
执行命令:npm run echarts -s 并回车
看到这样的提示代表安装成功 PS：网络不好的情况建议用cnpm淘宝镜像（全局终端执行命令：npm i -g cnpm --registry=https://registry.npm.taobao.org）
下载china.js

引入
import echarts from 'echarts/lib/echarts'; import '@/map/china.js';
写一个echarts容器 绑定ref
<div class="wrapper"> <div class="map-container" style="width: 100%; height: 100%" ref="myEchart" ></div> </div>
配置option (有必要的注释都已标记)

初始化echarts就可以了
this.myEchart = echarts.init(this.$refs.myEchart); this.myEchart.setOption(option);
