我无法完全看到如何删除WPFToolkit图中的标记。我可以看到它们是下面XAML中的省略号，但我似乎无法成功更改任何参数以获得更改它们的大小，或者删除它们。有什么想法吗？
以下是我一直在使用的XAML（仍然需要WPFToolkit）。

答案 0 :(得分：2)
您可以通过设置LineSeries的DataPointStyle依赖属性来更改任何参数。例如，......
<!-- Power curve -->
<chartingToolkit:LineSeries
Title="Power"
ItemsSource="{StaticResource EngineMeasurementCollection}"
IndependentValueBinding="{Binding Speed}"
DependentValueBinding="{Binding Power}">
<!-- Changing the data point style -->
<chartingToolkit:LineSeries.DataPointStyle>
<Style TargetType="chartingToolkit:LineDataPoint">
<Setter Property="Width" Value="20"/>
<Setter Property="Height" Value="20"/>
</Style>
</chartingToolkit:LineSeries.DataPointStyle>
<!-- Vertical axis for power curve -->
etc...
</chartingToolkit:LineSeries>
我不确定要删除它们。您可以使用相同的方法将样式的可见性设置为折叠，但这似乎不是最佳答案？
