求会用pyecharts做下面这个图的轮播图

Question

主要问题是数据不会加，可以参考https://gallery.pyecharts.org/#/Pie/nested_pies%E4%BB%A3%E7%A0%81

Answer 1

按这个例子改下数据及饼图生成部分即可。

用pyecharts 实现按时间线轮播数据饼图_预则立-CSDN博客 上次做了一个轮播柱状图的例子现在做一个饼图的例子 ， 例子代码基于 pyecharts 1.7 ,如果是高版本， 要改对应的函数。Python 3.7.3pyecharts Version: 1.7.1完成后，大概就长这个样子上代码 , pie_base 是建一个pie 对象。 create_timeline_data是建立一个轮播图。 # encoding: utf-8"""@author: 陈年椰子@contact: [e-mail]... https://blog.csdn.net/seakingx/article/details/122470088
