c# – wpf oxyplot – 单击datapoint时更改弹出窗口
作者:互联网
我正在使用带有wpf的oxyplot,如果点击一个数据点,我想更改弹出窗口.
有可能改变吗?我看了几个例子,展示了如何获得点击的点,但没有关于改变样式.
谢谢
解决方法:
该弹出窗口在OxyPlot的源代码中称为Tracker.
您可以通过OxyPlot.Wpf.PlotView.DefaultTrackerTemplate在XAML中定义其ControlTemplate:
<oxy:PlotView Model="{Binding SomePlotModel}">
<oxy:PlotView.DefaultTrackerTemplate>
<ControlTemplate>
<!-- Put your content here-->
</ControlTemplate>
</oxy:PlotView.DefaultTrackerTemplate>
</oxy:PlotView>
如果每个系列数据需要不同的跟踪器,则使用OxyPlot.Wpf.PlotView.TrackerDefinitions.例如,如果您的LineSeries具有TrackerKey =“LineSeriesXyzTrackerKey”,则将其跟踪器定义为:
<oxy:PlotView Model="{Binding SomePlotModel}">
<oxy:PlotView.TrackerDefinitions>
<oxy:TrackerDefinition TrackerKey="LineSeriesXyzTrackerKey">
<oxy:TrackerDefinition.TrackerTemplate>
<ControlTemplate>
<!-- Put your content here-->
</ControlTemplate>
</oxy:TrackerDefinition.TrackerTemplate>
<oxy:TrackerDefinition TrackerKey="SomeOtherTrackerKey">
<oxy:TrackerDefinition.TrackerTemplate>
<ControlTemplate>
<!-- Put your content here-->
</ControlTemplate>
</oxy:TrackerDefinition.TrackerTemplate>
</oxy:TrackerDefinition>
</oxy:PlotView.TrackerDefinitions>
ControlTemplate的DataContext是TrackerHitResult,您可以在此处查看可用的属性:

How can I show the plot points in Oxyplot for a line Graph?
