前言:
此时我们对“mysql数据可视化大屏”大概比较讲究,咱们都想要知道一些“mysql数据可视化大屏”的相关内容。那么小编在网络上汇集了一些关于“mysql数据可视化大屏””的相关内容,希望朋友们能喜欢,咱们快快来学习一下吧!近年来,数据可视化大屏的出现,掀起一番又一番的浪潮,众多企业主纷纷想要打造属于自己的“酷炫吊炸天”的霸道总裁大屏驾驶舱。今天为大家来分享的是 物流大数据服务平台。
话不多说,开始分享干货,欢迎讨论!
首先看动态效果图 :一、 确定需求方案
最终样式图
1、确定产品上线部署的屏幕LED分辨率
1920px*1080px,F11全屏后占满整屏且无滚动条。其它分辨率也可自适应。
2、功能模块
湖南货物收入湖南省地图全国地图货物周转量湖南高速公路湖南省飞机场湖南省业务量货物周转量
3、部署方式
基于免安装可执行程序:支持Windows、Linux、Mac等各种操作系统;将程序复制到服务器上即可,无需其它环境依赖;
观看方式:既可在服务器上直接观看程序界面,也可在远程用浏览器打开播放,例如Chrome浏览器、360浏览器等。
二、整体架构设计
1、前端基于Echarts开源库设计,使用WebStorm编辑器;
2、后端基于Python Web实现,使用Pycharm编辑器;
3、数据传输格式:JSON;
4、数据源类型:目前已支持PostgreSQL、MySQL、Oracle、Microsoft SQL Server、SQLite、Excel表格等,还可以定制HTTP API接口方式或其它类型数据库。
5、数据更新方式:摒弃了前端页面定时拉取的方式(这种方式带来严重的资源浪费),采用后端数据实时更新,实时推送到前端展示;
三、编码实现 (基于篇幅及可读性考虑,此处展示部分关键代码)
1、前端html代码:
