如何优雅得搭建可视化大屏呢？
郑重阐明:本文不间接提供最终代码
白嫖怪福音,收费开源---pyechart官网
通过多年钻研,终于被我这只菜鸡整进去了！手动滑稽...
咱们先上一张效果图瞧瞧:
注:数据纯属虚构
看起来如同是那么回事？！？！
上面咱们步入正题↓
实现过程:
- 爬取业务零碎数据,存储至mysql(数据体量大举荐)或者excel内都可
- 利用pyecharts可视化
- 嵌入到前端框架内
- 局域网共享
须要用到的知识点:
- python、javascript、html、css、mysql、pandas、pyecharts
版本不兼容解决方案:
- python 版本 :3.6
- pyecharts 版本:1.9.0
- CMD装置命令: pip install pyecharts=1.9.0
- 如果已装置 pyecharts 然而不晓得版本怎么办?
- CMD命令: pip list内查看即可

布局款式设置:
如何把这些图表组合起来呢？
集体抉择比拟无脑的一种,
利用BeautifulSoup获取标签设置style
想让它去哪儿就去哪儿
css款式如果遗记-请点击它 菜鸟CSS官网教学示例
示例:
with open("YG_view.html", "r+", encoding='utf-8') as html: html_bf = BeautifulSoup(html, 'lxml') # 款式 lables = html_bf.select('tbody') lables[0]["style"] = "text-align:center;"提醒:个别一个图表在一个div内,获取div标签循环遍历设置即可
