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

问题

Here is the xaml code to my graph:

<oxy:Plot HorizontalAlignment="Left" 
              Height="222" 
              Margin="0,49,0,0" 
              VerticalAlignment="Top" 
              Width="870" 
              Background="Transparent" 
              PlotAreaBorderColor="White" 
              LegendBorder="Transparent"
              Name="viewCountPlot"
              Title="Videos Watched"
              TextColor="White" IsLegendVisible="False" IsManipulationEnabled="False" IsMouseWheelEnabled="False">
        <oxy:Plot.Axes>
            <oxy:DateTimeAxis Name="datetimeAxis" Position="Bottom" MajorGridlineColor="#40FFFFFF" TicklineColor="White" StringFormat="M/d/yy" IntervalType="Days" ShowMinorTicks="False"/>
        </oxy:Plot.Axes>
        <oxy:Plot.Series>
            <oxy:LineSeries 
                Name="viewCountSeries" 
                Title="Videos Viewed"
                DataFieldX="Date" 
                DataFieldY="Value" 
                Color="#CCFA6800" 
                StrokeThickness="2" 
                TrackerFormatString="Date: {2:M/d/yy}&#x0a;Value: {4}"
                ItemsSource="{Binding PlotItems}" MarkerStroke="#FFFDFDFD" />
        </oxy:Plot.Series>
        <oxy:Plot.DefaultTrackerTemplate>
            <ControlTemplate>
                <Canvas>
                    <Grid Canvas.Left="{Binding Position.X}" Canvas.Top="{Binding Position.Y}">
                        <Ellipse Fill="White" Width="12" Height="12" HorizontalAlignment="Left" VerticalAlignment="Top">
                            <Ellipse.RenderTransform>
                                <TranslateTransform X="-6" Y="-6" />
                            </Ellipse.RenderTransform>
                        </Ellipse>
                        <TextBlock Foreground="{DynamicResource OrangeTextColor}" Text="{Binding}" Margin="-60 -40 0 0" />
                    </Grid>
                </Canvas>
            </ControlTemplate>
        </oxy:Plot.DefaultTrackerTemplate>
    </oxy:Plot>

In the plot Series is there any way to show the plot points as circles or something of that nature?

Here is an example image of what I mean, each plot point has a small circle associated with it:

From the linked discussion:

This should be covered by the Marker* properties in the LineSeries See examples in the Example browser.

It looks like you have to set MarkerFill and MarkerType. To show only markers (and no line), set the Color to Transparent.

<oxy:LineSeries ItemsSource="{Binding MyDataPoints}" 
                Color="Transparent" 
                MarkerFill="SteelBlue" 
                MarkerType="Circle" />
