WPF LiveCharts.WPF 封装实现

下面是一个完整的 WPF LiveCharts.WPF 封装实现，提供了常用图表的简单使用方式，并支持数据绑定和更新。

一、LiveCharts.WPF 封装类

1. 图表基类 (ChartBase.cs)

using LiveCharts;
using LiveCharts.Wpf;
using System.Collections.Generic;
using System.Windows.Controls;
using System.Windows.Media;namespace WpfSupervisor.Charts
{public abstract class ChartBase : UserControl{protected ChartValues<double> _chartValues = new ChartValues<double>();protected SeriesCollection _seriesCollection = new SeriesCollection();protected LiveCharts.Wpf.Axis _xAxis = new LiveCharts.Wpf.Axis();protected LiveCharts.Wpf.Axis _yAxis = new LiveCharts.Wpf.Axis();static ChartBase(){// 设置默认样式DefaultStyles.Initialize();}public ChartBase(){InitializeComponent();SetupChart();}protected abstract void InitializeComponent();protected abstract void SetupChart();public void UpdateData(IEnumerable<double> newData){_chartValues.Clear();foreach (var value in newData){_chartValues.Add(value);}OnPropertyChanged(nameof(ChartValues));}public void AddDataPoint(double value){_chartValues.Add(value);OnPropertyChanged(nameof(ChartValues));}public void ClearData(){_chartValues.Clear();OnPropertyChanged(nameof(ChartValues));}public SeriesCollection SeriesCollection{get => _seriesCollection;set{_seriesCollection = value;OnPropertyChanged(nameof(SeriesCollection));}}public ChartValues<double> ChartValues{get => _chartValues;set{_chartValues = value;OnPropertyChanged(nameof(ChartValues));}}public LiveCharts.Wpf.Axis XAxis{get => _xAxis;set{_xAxis = value;OnPropertyChanged(nameof(XAxis));}}public LiveCharts.Wpf.Axis YAxis{get => _yAxis;set{_yAxis = value;OnPropertyChanged(nameof(YAxis));}}public event System.ComponentModel.PropertyChangedEventHandler PropertyChanged;protected void OnPropertyChanged(string propertyName){PropertyChanged?.Invoke(this, new System.ComponentModel.PropertyChangedEventArgs(propertyName));}}
}

2. 折线图封装 (LineChartControl.xaml & LineChartControl.xaml.cs)

​​LineChartControl.xaml​​

<UserControl x:Class="WpfSupervisor.Charts.LineChartControl"xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"xmlns:lvc="clr-namespace:LiveCharts.Wpf;assembly=LiveCharts.Wpf"xmlns:local="clr-namespace:WpfSupervisor.Charts"x:Name="root"><lvc:CartesianChart Series="{Binding SeriesCollection, ElementName=root}" Axes="{Binding Axes, ElementName=root}"LegendLocation="Right"Hoverable="False"DataTooltip="{x:Null}"><lvc:CartesianChart.ChartLegend><lvc:DefaultLegend BulletSize="10" /></lvc:CartesianChart.ChartLegend><lvc:CartesianChart.Zoom><lvc:ZoomingOptions ZoomMode="X" /></lvc:CartesianChart.Zoom></lvc:CartesianChart>
</UserControl>

​​LineChartControl.xaml.cs​​

using LiveCharts;
using LiveCharts.Wpf;
using System.Collections.Generic;
using System.Windows.Controls;
using System.Windows.Media;namespace WpfSupervisor.Charts
{public partial class LineChartControl : ChartBase{public static readonly DependencyProperty TitleProperty =DependencyProperty.Register("Title", typeof(string), typeof(LineChartControl), new PropertyMetadata("折线图", OnTitleChanged));public static readonly DependencyProperty LineColorProperty =DependencyProperty.Register("LineColor", typeof(Brush), typeof(LineChartControl), new PropertyMetadata(new SolidColorBrush(Colors.Blue), OnLineColorChanged));public string Title{get => (string)GetValue(TitleProperty);set => SetValue(TitleProperty, value);}public Brush LineColor{get => (Brush)GetValue(LineColorProperty);set => SetValue(LineColorProperty, value);}public LineChartControl(){InitializeComponent();}protected override void InitializeComponent(){// 已在XAML中定义}protected override void SetupChart(){_seriesCollection = new SeriesCollection{new LineSeries{Title = Title,Values = ChartValues,PointGeometrySize = 5,Stroke = LineColor,Fill = Brushes.Transparent}};_xAxis = new LiveCha
