C#-WPF-控件-LiveChart图表-线性2(LineSeries)-数据绑定

知识点1. 数据绑定 2. X轴上显示点数主类中3. 添加随机值在图表中 值针对Y轴值4. 清空图表5. 图标titel显示实例lvc:CartesianChart x:NameLiveCharts1 Margin10,200,185,10 Series{Binding SeriesCollection} //BeanDataKalman.cs中 Background#FFF8FCFD LegendLocationTop /lvc:CartesianChartBeanDataKalman.csusing System; using System.Collections.Generic; using System.ComponentModel; using System.Runtime.CompilerServices; using System.Text; using System.Xml.Linq; using LiveCharts; namespace Wpf_Math.BeanDatas { public class BeanDataKalman : INotifyPropertyChanged { private string _msgTips; private SeriesCollection _seriesCollection; public BeanDataKalman() { // 在构造函数中初始化 _seriesCollection new SeriesCollection(); } public string MsgTips { get _msgTips; set { _msgTips value; OnPropertyChanged(); } } public SeriesCollection SeriesCollection { get _seriesCollection; set { if (_seriesCollection ! value) { _seriesCollection value; OnPropertyChanged(); } } } public event PropertyChangedEventHandler?
