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(
            document.getElementById('65e195a41f494479b5c980b285573936'), 'white', {renderer: 'canvas'});
        // 创建图表各个参数
        var option_65e195a41f494479b5c980b285573936 = {
