How can I show the plot points in Oxyplot for a line Graph?
提问by JBurlison
Here is the xaml code to my graph:
这是我的图表的 xaml 代码：
<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}
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?
在情节系列中，有没有办法将情节点显示为圆圈或类似的东西？
Here is an example image of what I mean, each plot point has a small circle associated with it:
这是我的意思的示例图像，每个绘图点都有一个与之关联的小圆圈：

From the linked discussion:
来自链接的讨论：
This should be covered by the
Marker*properties in theLineSeriesSee examples in the Example browser.
这应该包含 在示例浏览器
Marker*中的LineSeries查看示例中的属性中。
It looks like you have to set MarkerFilland MarkerType. To show only markers (and no line), set the Colorto Transparent.
看起来你必须设置MarkerFill和MarkerType。要仅显示标记（没有线），设置Color到Transparent。
<oxy:LineSeries ItemsSource="{Binding MyDataPoints}"
Color="Transparent"
MarkerFill="SteelBlue"
MarkerType="Circle" />
