在WPF将接收到的数据用Livecharts实时曲线显示

首先,您需要引用LiveCharts库。可以通过NuGet包管理器安装LiveCharts.Wpf。
接下来,您需要在.xaml文件中添加Chart控件。例如:
```
<Window x:Class="WpfApp1.MainWindow"
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"
Title="MainWindow" Height="350" Width="525">
<Grid>
<lvc:CartesianChart Series="{Binding SeriesCollection}" LegendLocation="Right"/>
</Grid>
</Window>
```
在.cs文件中,您需要创建SeriesCollection和ChartValues对象,并在接收到数据时将数据添加到ChartValues中。例如:
```
using LiveCharts;
using LiveCharts.Wpf;
using System.Collections.ObjectModel;
public partial class MainWindow : Window
{
public SeriesCollection SeriesCollection { get; set; }
public ObservableCollection<double> ChartValues { get; set; }
public MainWindow()
{
InitializeComponent();
ChartValues = new ObservableCollection<double>();
SeriesCollection = new SeriesCollection
{
new LineSeries
{
Title = "Data",
Values = ChartValues
}
};
DataContext = this;
}
// Method to add data to the chart
private void AddData(double newData)
{
ChartValues.Add(newData);
}
}
```
在接收到数据时,调用AddData方法,将数据添加到ChartValues中。当ChartValues更新时,LiveCharts会自动更新图表。例如:
```
private void OnDataReceived(object sender, DataReceivedEventArgs e)
{
double newData = Convert.ToDouble(e.Data);
AddData(newData);
}
```
这样,您就可以使用LiveCharts实时显示曲线了。
