Golang 数据可视化利器 go-echarts ，实际使用

朴灿烈づ我的快乐病毒、 2022-11-26 11:55 311阅读 0赞

今天就来聊聊go里面如何绘制echarts图，

需求：使用go来生成自动化巡检报告，数据库的性能采集也是通过go来实现的，这里就不多说，那如何能够直观的展示监控数据呢，当然前面我有写过flask +python+vue 的监控系统：[https://blog.csdn.net/shiyu1157758655/article/details/103278459][https_blog.csdn.net_shiyu1157758655_article_details_103278459]

今天我要做的是，不通过监控系统，直接把想要的数据展示出来，生成html文件，这里主要就是介绍golang 中 go-echarts 如何使用 ，闲话少说，直接上图（部分图）

那上面的是如何实现的呢，直接上代码
