Line chart with symbols?

[Brian]

Is it possible to produce a line chart that has symbols for various points on the chart?  See the attached image for an example of what I'm referring to.
I'd like to create a line chart that has a symbol every nth point.  For example, the attached image is a line chart that has a symbol every 10th point.
Tks.

Hi Brian,

You can use a similar approach as the shown in this example. The main idea is to bind the visibility in the point marks' template to a property in your view model.

Here is the default point mark's template:

<Style  x:Key="CustomPoint" TargetType="telerikCharting:PointMark">
    <Setter Property="Size" Value="10" />
    <Setter Property="Template">
        <Setter.Value>
            <ControlTemplate TargetType="telerikCharting:PointMark">
                <Canvas>
                    <Path x:Name="PART_PointMarkPath"
                        Canvas.Left="{TemplateBinding PointMarkCanvasLeft}"
                        Canvas.Top="{TemplateBinding PointMarkCanvasTop}"
                        Style="{TemplateBinding ShapeStyle}"
                        Width="{TemplateBinding Size}"
                        Height="{TemplateBinding Size}"
                        Stretch="Uniform">
                        <Path.Data>
                            <PathGeometry x:Name="PART_PointMarkPathGeometry" />
                        </Path.Data>
                    </Path>
                </Canvas>
            </ControlTemplate>
        </Setter.Value>
    </Setter>
</Style>

and this style can be set through the exposed PointMarkItemStyle property of the Line series definition.
