WPF真入门教程27--项目案例--设备数据实时监测-编程知识

1、上图看效果

今天要做的一个案例是这样的效果，它能实时监测车间设备有关数据，并以表格和图形显示在界面上，这个比上个案例要复杂些，颜值也高些，通过这个来巩固wpf的技能，用到了命令绑定，样式资源，表格数据，图形控件livechart。将前面25的内容熟悉起来，就可以自己动手做这个案例了。

2、创建wpf项目

3、 UI布局分析

整个界面是一个表格，表格分二行，第一行是标题栏，第二行是数据栏，

第二行分2列，第1列放表格控件，第2列放图形控件

第一行分7列，放7个控件

1、第一行

2、第二行

WPF中的布局是表格布局风格，通过一个个的细化组合形成UI，完整代码如下，大家可以仔细看看，注释都有，仔细体会下，不算难：

</Window>

3、样式资源

样式文件就是WEB中的css属性设置，需要精细的考虑，软件的界面就是一个人的颜值，可以看看，用的时候改改。
