我正在尝试将图表导出到 PNG。那是我的代码：

图表.xaml

<Window x:Class="P1.Chart"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:oxy="http://oxyplot.org/wpf"
    xmlns:local="clr-namespace:P1"
    Title="Example 1 (WPF)" Height="800" Width="800"
    DataContext="{Binding RelativeSource={RelativeSource Self}}">

<Grid>
    <oxy:Plot>
        <oxy:Plot.Axes>
            <oxy:LinearAxis Position="Bottom" Minimum="-20" Maximum="20" />
            <oxy:LinearAxis Position="Left" Minimum="-20" Maximum="20" />
        </oxy:Plot.Axes>

        <oxy:Plot.Series>
            <oxy:LineSeries ItemsSource="{Binding Points1}" LineStyle="None"  MarkerType="Circle" MarkerSize="3" MarkerFill="Red" Title="Point 1"/>
            <oxy:LineSeries ItemsSource="{Binding Points2}" LineStyle="None"  MarkerType="Circle" MarkerSize="3" MarkerFill="Green" Title="Point 2"/>
            <oxy:LineSeries ItemsSource="{Binding Points3}" LineStyle="None"  MarkerType="Circle" MarkerSize="3" MarkerFill="Blue" Title="Point 3"/>   
        </oxy:Plot.Series>
    </oxy:Plot>
</Grid>

图表.xaml.cs

    namespace P1
{
    public partial class Chart: Window
    {
        public IList<DataPoint> Points1 { get;  set; }
        public …
