一共有两种方式来实现一种是使用第三方的框架来实现另外一种是自己通过原创代码来一步步实现本文主要介绍这两种曲线的实现方式。
1.首先我创建一个wpf的解决方案项目。 2.在NuGet中添加 DynamicDataDisplay 项目支持 为了展示我们的UI界面我们还添加了一个第三方的样式框架 Panuon.UI.Silver 3.我们在MainWindow.xaml文件中添加如下代码
d3:ChartPlotter x:Nameplotterd3:Header x:NameHeaderTitle VisibilityVisible Content这是曲线的标题 FontSize14 HorizontalAlignmentCenter /d3:VerticalAxisTitle ContentValue FontSize14 VisibilityCollapsed/d3:HorizontalAxisTitle Content时间 FontSize14 VisibilityCollapsed//d3:ChartPlotter 4.接下来我们就开始实现后台代码部分
