目录环境相关实现思路（需要理解的请结合代码来看）代码：成果展示参考博客在Django开发过程中，遇到了需要图表进行数据可视化的需要。因此查询了相关文档，并记录下如何实现与图表的数据交
在Django开发过程中，遇到了需要图表进行数据可视化的需要。因此查询了相关文档，并记录下如何实现与图表的数据交互。 本人是个前端小白，只会改不会写（套模板）。
仅供参考！！！
DjanGo （版本不限，当然不同的版本有不同的后端代码写法。本文环境为Django 3.1）
echarts （前端的画图框架，导入js包即可） 点击网址可以找到模板 网址
Jquery （用于ajax请求 导入JS包即可 在文中会有JS包地址）
urls.py
re_path('ajax_line/', views.ajax_line, name='ajax_line'),ajax请求接口：
