WPF图表:如何折叠lineseries中的数据点

Question

我在图表中有多个系列.首先绘制图表线,然后点线.这很烦人,大点的大小使大型数据集变得毫无用处.目前我正在为每个lineseries做这个...

    <chartingToolkit:LineSeries
          Title="Socket 2"
          Name="LineSocket2"
          LegendItemStyle ="{StaticResource LegendItemStyle}"
          IndependentValueBinding="{Binding timestamp}"
          DependentValueBinding="{Binding wattage}"
          ToolTip="Socket 2">

        <chartingToolkit:LineSeries.DataPointStyle>
            <Style TargetType="{x:Type chartingToolkit:LineDataPoint}">
                <Setter Property="Visibility" Value="Collapsed"/>
            </Style>
        </chartingToolkit:LineSeries.DataPointStyle>

    </chartingToolkit:LineSeries>

但它没有做我想要的.

怎么做到呢？

如果它对任何人都有帮助,以下方法对我有用:

                <chartingToolkit:Chart DataContext="1,10 2,20 3,30 4,40" HorizontalAlignment="Stretch" Margin="-1,14,0,0" Name="chart1" Title="Chart Title" VerticalAlignment="Stretch" Width="806" Height="Auto">
                    <chartingToolkit:LineSeries Name="Series1" DependentValuePath="X" IndependentValuePath="Y" ItemsSource="{Binding}">
                        <chartingToolkit:LineSeries.DataPointStyle>
                            <Style TargetType="chartingToolkit:LineDataPoint">
                                <Setter Property="Opacity" Value="0" />
                                <Setter Property="Background" Value="Blue" />
                            </Style>
                        </chartingToolkit:LineSeries.DataPointStyle>
                    </chartingToolkit:LineSeries>
                </chartingToolkit:Chart>
