Django （版本不限，當(dāng)然不同的版本有不同的后端代碼寫法。本文環(huán)境為Django 3.1）
echarts （前端的畫圖框架，導(dǎo)入JS包即可）點擊網(wǎng)址可以找到模板網(wǎng)址
JQuery （用于Ajax請求導(dǎo)入JS包即可在文中會有JS包地址）

實現(xiàn)思路（需要理解的請結(jié)合代碼來看）

后端方面主要涉及到了ajax，其實就是前端對后端請求一個特定的地址，后端收到請求后，將數(shù)據(jù)整理并打包成json格式向前端發(fā)送，有點類似于在寫API接口。
前端方面。主要有兩個點：echarts 和Ajax 。
echarts 中可以看到，生成的模板里面有2個data項，用于儲存數(shù)據(jù)信息制作表格。（不同的圖表有不同的數(shù)據(jù)點，本文只有2個data項，生成折線圖）
Ajax 用于向后端發(fā)送請求。
在編寫過程中，先將echarts 表的數(shù)據(jù)項清空（data : []）。后續(xù)通過ajax請求向后端請求數(shù)據(jù)包，并提取對應(yīng)的數(shù)據(jù)加入到echarts 表的數(shù)據(jù)項中。

代碼：

urls.py

re_path('ajax_line/', views.ajax_line, name='ajax_line'),

ajax請求接口：
