我们可以使用Toolkit Chart 控件去绘制图形

添加System.Windows.Controls.DataVisualization.Toolkit.dll 引用后，XAML中可以以下面的方式使用

<Window x:Class="WpfChart3._5.MainWindow"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        xmlns:datavis="clr-namespace:System.Windows.Controls.DataVisualization;assembly=System.Windows.Controls.DataVisualization.Toolkit" 
        xmlns:charting="clr-namespace:System.Windows.Controls.DataVisualization.Charting;assembly=System.Windows.Controls.DataVisualization.Toolkit"
        Title="MainWindow" Height="350" Width="525">
    <Grid HorizontalAlignment="Stretch" VerticalAlignment="Stretch" Margin="10" Grid.Column="1" Grid.Row="0">
        <charting:Chart x:Name="waitingtasks" BorderBrush="Transparent" BorderThickness="0" VerticalAlignment="Stretch" Title="Waiting Tasks">
            <charting:Chart.TitleStyle>
                <Style TargetType="datavis:Title">
                    <Setter Property="HorizontalAlignment" Value="Left"/>
                    <Setter Property="Foreground" Value="White"/>
                </Style>
            </charting:Chart.TitleStyle>
            <charting:Chart.LegendStyle>
                <Style TargetType="datavis:Legend">
                    <Setter Property="Width" Value="0" />
                </Style>
            </charting:Chart.LegendStyle>
            <charting:Chart.Axes>
                <charting:LinearAxis Orientation="X" Title="Time" Interval="20" ShowGridLines="False"/>
                <charting:LinearAxis Title="Number of Waiting Tasks" Orientation="Y" Interval="5" ShowGridLines="False"/>
            </charting:Chart.Axes>
            <charting:LineSeries DependentValuePath="Value" IndependentValuePath="Key" ItemsSource="{Binding}" IsSelectionEnabled="True" 
                                    AnimationSequence="FirstToLast"/>
        </charting:Chart>
    </Grid>
</Window>
