WPF實現(xiàn)曲線數(shù)據(jù)展示
更新時間：2024年12月27日 08:55:04 作者：洱海之月
這篇文章將以動數(shù)據(jù)分析為例為大家詳細(xì)介紹wpf實現(xiàn)曲線數(shù)據(jù)展示與函數(shù)曲線展示的方法,文中的示例代碼講解詳細(xì),感興趣的小伙伴可以參考一下
wpf實現(xiàn)曲線數(shù)據(jù)展示，函數(shù)曲線展示，實例：震動數(shù)據(jù)分析為例。
如上圖所示，如果你想實現(xiàn)上圖中的效果，請詳細(xì)參考我的內(nèi)容。
一共有兩種方式來實現(xiàn)，一種是使用第三方的框架來實現(xiàn)，另外一種是自己通過原創(chuàng)代碼來一步步實現(xiàn)，本文主要介紹這兩種曲線的實現(xiàn)方式。
1.首先我創(chuàng)建一個wpf的解決方案項目。
2.在NuGet中添加 DynamicDataDisplay 項目支持
為了展示我們的UI界面，我們還添加了一個第三方的樣式框架 Panuon.UI.Silver
3.我們在MainWindow.xaml文件中添加如下代碼
<d3:ChartPlotter x:Name="plotter">
<d3:Header x:Name="HeaderTitle" Visibility="Visible" Content="這是曲線的標(biāo)題" FontSize="14" HorizontalAlignment="Center" />
<d3:VerticalAxisTitle Content="Value" FontSize="14" Visibility="Collapsed"/>
<d3:HorizontalAxisTitle Content="時間" FontSize="14" Visibility="Collapsed"/>
</d3:ChartPlotter>
4.接下來我們就開始實現(xiàn)后臺代碼部分
