wpf实现曲线数据展示，函数曲线展示，实例：震动数据分析为例。
如上图所示，如果你想实现上图中的效果，请详细参考我的内容，创作不易，给个赞吧。
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:Name="plotter"><d3:Header x:Name="HeaderTitle" Visibility="Visible" Content="这是曲线的标题" FontSize="14" HorizontalAlignment="Center" /><d3:VerticalAxisTitle Content="Value" FontSize="14" Visibility="Collapsed"/><d3:HorizontalAxisTitle Content="时间" FontSize="14" Visibility="Collapsed"/></d3:ChartPlotter>
4.接下来我们就开始实现后台代码部分
