Wpf oxyplot - change popup when datapoint is clicked

Question

I am using oxyplot with wpf and I want to change the popup if I click datapoint.

Is it possible to change? I saw several examples that show how to get a click, but nothing to change the style.

thank

The popup is called Trackerin the source code of OxyPlot. You can define its ControlTemplate in XAML through OxyPlot.Wpf.PlotView.DefaultTrackerTemplateas:

<oxy:PlotView Model="{Binding SomePlotModel}">
  <oxy:PlotView.DefaultTrackerTemplate>
    <ControlTemplate>
       <!-- Put your content here-->
    </ControlTemplate>
   </oxy:PlotView.DefaultTrackerTemplate>
</oxy:PlotView>

If a different tracker is needed for each data series, use OxyPlot.Wpf.PlotView.TrackerDefinitions. For example, if you have LineSeries with TrackerKey="LineSeriesXyzTrackerKey", then its tracker determines as:

<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>
