问题描述
我不太明白如何删除 WPFToolkit 图表中的标记.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更改它们的大小或删除它们.有什么想法吗?
I can't quite see how to remove the markers in a WPFToolkit graph. I can see they are the ellipses in the XAML below, but I can't seem to successfully change any of the parameters to get the size of them to change, OR to remove them. Any ideas?
这是 XAML(它仍然需要 WPFToolkit)我一直在用作测试.

推荐答案
您可以通过设置 LineSeries 的 DataPointStyle 依赖属性来更改任何参数.例如，...
You can change any of the parameters by setting the DataPointStyle dependancy property of your LineSeries. For example, ...
<!-- 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>
我不确定是否要删除它们.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?
I'm not sure about removing them. You could use the same method to set the style's visibility to collapsed but that doesn't seem like the best answer?
