wpf oxyplot -- change popup when datapoint is clicked

I am using oxyplot with wpf and I want to change the popup if a datapoint gets clicked. OxyplotDataPointClick

Is it possible to change? I saw a few examples that show how to get the clicked point but nothing about changeing the style.

Thank You

  • The popup is called Tracker in OxyPlot's source code. You can define its ControlTemplate in XAML via OxyPlot.Wpf.PlotView.DefaultTrackerTemplate as: 

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

    If each series data need different tracker, then use OxyPlot.Wpf.PlotView.TrackerDefinitions. For example, if your have a LineSeries with TrackerKey="LineSeriesXyzTrackerKey", then defines its tracker 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>

    The DataContext for the ControlTemplate is a TrackerHitResult, you can view what properties are available here: https://github.com/oxyplot/oxyplot/blob/master/Source/OxyPlot/PlotController/Manipulators/TrackerHitResult.cs
