从silverlight线或区域系列中删除标记

是否可以轻松地从线系列或面积系列图表中删除数据点标记。我正在使用Silverlight工具箱图表。

找到它：

<chartingToolkit:AreaSeries ItemsSource="{Binding Path=ChartData}" DependentValuePath="used" IndependentValuePath="date" IsSelectionEnabled="True">
<chartingToolkit:AreaSeries.DataPointStyle>
    <Style TargetType="Control">
        <Setter Property="Visibility" Value="Collapsed" />
    </Style>
</chartingToolkit:AreaSeries.DataPointStyle>

找到它：

<chartingToolkit:AreaSeries ItemsSource="{Binding Path=ChartData}" DependentValuePath="used" IndependentValuePath="date" IsSelectionEnabled="True">
<chartingToolkit:AreaSeries.DataPointStyle>
    <Style TargetType="Control">
        <Setter Property="Visibility" Value="Collapsed" />
    </Style>
</chartingToolkit:AreaSeries.DataPointStyle>
