title: How can I show the plot points in Oxyplot for a line Graph?
body: <p>Here is the xaml code to my graph:</p>
  
  <pre><code>&lt;oxy:Plot HorizontalAlignment="Left" 
                Height="222" 
                Margin="0,49,0,0" 
                VerticalAlignment="Top" 
                Width="870"

                PlotAreaBorderColor="White" 
                LegendBorder="Transparent"
                Name="viewCountPlot"
                Title="Videos Watched"
                TextColor="White" IsLegendVisible="False" IsManipulationEnabled="False" IsMouseWheelEnabled="False"&gt;
          &lt;oxy:Plot.Axes&gt;

          &lt;/oxy:Plot.Axes&gt;
          &lt;oxy:Plot.Series&gt;
              &lt;oxy:LineSeries 
                  Name="viewCountSeries" 
                  Title="Videos Viewed"
                  DataFieldX="Date" 
                  DataFieldY="Value" 
                  Color="#CCFA6800" 
                  StrokeThickness="2" 
                  TrackerFormatString="Date: {2:M/d/yy}&amp;#x0a;Value: {4}"
                  ItemsSource="{Binding PlotItems}" MarkerStroke="#FFFDFDFD" /&gt;
          &lt;/oxy:Plot.Series&gt;
          &lt;oxy:Plot.DefaultTrackerTemplate&gt;
              &lt;ControlTemplate&gt;
                  &lt;Canvas&gt;
                      &lt;Grid Canvas.Left="{Binding Position.X}" Canvas.Top="{Binding Position.Y}"&gt;
                          &lt;Ellipse Fill="White" Width="12" Height="12" HorizontalAlignment="Left" VerticalAlignment="Top"&gt;
                              &lt;Ellipse.RenderTransform&gt;
                                  &lt;TranslateTransform X="-6" Y="-6" /&gt;
                              &lt;/Ellipse.RenderTransform&gt;
                          &lt;/Ellipse&gt;
                          &lt;TextBlock Foreground="{DynamicResource OrangeTextColor}" Text="{Binding}" Margin="-60 -40 0 0" /&gt;
                      &lt;/Grid&gt;
                  &lt;/Canvas&gt;
              &lt;/ControlTemplate&gt;
          &lt;/oxy:Plot.DefaultTrackerTemplate&gt;
      &lt;/oxy:Plot&gt;

  <p>In the plot Series is there any way to show the plot points as circles or something of that nature?</p>
  
  <p>Here is an example image of what I mean, each plot point has a small circle associated with it:</p>
