@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

链接: https://pan.baidu.com/s/1EODVh9tJNEbFebbrhKyd_Q 提取码: gjz4

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);
