第一步下载模块
npm install echarts --save第二步引入
import * as echarts from 'echarts';
require('echarts/extension/bmap/bmap');
第三步设置参数
<!-- 为 ECharts 准备一个定义了宽高的 DOM -->
<div id="main" style="width: 600px;height:400px;"></div>第四步写echarts图库
export default {
data(){
return{
}
},
mounted(){
this.chinachart = echarts.init(document.getElementById('main'));

this.chinachart.setOption(this.option)

}到这里应该会报错
我们去public文件的index.html
加上以下内容就ok了
<script type="text/javascript" src="http://api.map.baidu.com/api?v=3.0&ak=nSxiPohfziUaCuONe4ViUP2N"></script>nSxiPohfziUaCuONe4ViUP2N这个是密钥
ok这样就完成了
前往低代码交流专区
