前言

  最近做软件工程课设,因为需要用到可视化界面,经过仔细考察,在小组成员的建议下,最后决定使用XMAL做前台。

题目分析

  题目:物理环境包括温度、湿度、大气压力、光照等参量。软件能够以图形化方式,实时显示各参量的状态,比如,显示温度的实时曲线图。具有参量报警功能,能够提供出行意见,具有历史数据查询功能。假设数据以存放在数据库中或文件中。

  题目要求用图形化方式实时显示各参量状态,所以前台程序务必足够美观,选用XAML设计窗口界面,C#构建后台。这里主要总结一下XMAL。(我用到的,其实很少很水,主要是对一个构件的总结)。

代码以及注释:

  我主要负责生成图表部分,这里主要用了XMAL的一个控件 beto-rodriguez/Live-Charts https://github.com/beto-rodriguez/Live-Charts
