基于python利⽤pyecharts作图，实现图表随数据变化实时更新利⽤vue和echarts可以设置定时获取数据渲染页⾯，但pyecharts做的图在前端页⾯上为JS中的⼀个对象数据，（利⽤Python搭建服务器定时返回新作的图表太⿇烦⽬前不想这样做），那位⼤神有好办法不妨告知。。。
⽬前采⽤定时修改pyecharts图表对象的属性值，在渲染页⾯：
代码如下
<!--  初始化echarts图表 -->
var chart_65e195a41f494479b5c980b285573936 = echarts.init(
// 创建图表各个参数
var option_65e195a41f494479b5c980b285573936 = {
