element + vue + echarts realiza la conversión de vista y la adaptación del tamaño de la leyenda
Este tutorial es adecuado para principiantes, no rocíe.
La primera vez que escribo un blog, hay deficiencias, espero que todos lo señalen.

html
由于要是视图大小自适应页面并随页面大小变化,所以一定要在页面上方写入样式
<head>
<title>通知列表</title>
<#include "/header.html">
<!--引入echarts视图-->
<script type="text/javascript" src="${request.contextPath}/statics/libs/echarts.min.js"></script>
</head>
<style type="text/css">
.department-class{
width: 100%;
height: 100%;
}
</style>Parte del código de la página
graphicsShow se utiliza para controlar los gráficos que se muestran en la interfaz
