How do you change the size of the PointMarks in a RadChart?

[Geoff Hardy]

We would like to change the size of the PointMarks in the RadChart. Is there a simple way to do this?

We have tried the following:

seriesDefinition.PointMarkItemStyle = (Style) Resources["pointMarkItemStyle"];

With either of the following styles, this did not work:

    <Style TargetType="Charting:PointMark" x:Key="pointMarkItemStyle">
        <Setter Property="Size" Value="40"/>
    </Style>

    <Style TargetType="Charting:PointMark" x:Key="pointMarkItemStyle">
        <Setter Property="Width" Value="40"/>
        <Setter Property="Height" Value="40"/>
    </Style>

Hello Geoff Hardy,

Unfortunately I confirm that there is an issue with changing the size of the PointMarks. It is logged in our Public Issue Tracking system and you can check its status there.

At the present time you can change the size of your PointMarks as follows:

<Window x:Class="WpfApplication2Branch.Window1"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"

    <Window.Resources>
        <Style x:Name="CustomStyle" TargetType="chart:PointMark">
            <Setter Property="Template">
                <Setter.Value>
                    <ControlTemplate TargetType="chart:PointMark">
                        <Canvas>
                            <Path x:Name="PART_PointMarkPath"
                                  Canvas.Left="{TemplateBinding PointMarkCanvasLeft}"
                                  Canvas.Top="{TemplateBinding PointMarkCanvasTop}"
                                  Style="{TemplateBinding ShapeStyle}"
                                  Width="90"
                                  Height="90"
                                  Stretch="Fill">
                                <Path.Data>
                                    <PathGeometry x:Name="PART_PointMarkPathGeometry" />
                                </Path.Data>
                            </Path>
                        </Canvas>
                    </ControlTemplate>
                </Setter.Value>
            </Setter>
        </Style>
    </Window.Resources>
    <Grid>
        <telerik:RadChart x:Name="RadChart1" />
    </Grid>
</Window>

Code behind:

series1.Definition.PointMarkItemStyle = this.Resources["CustomStyle"] as Style;
RadChart1.DefaultView.ChartArea.DataSeries.Add(series1);

Hi again,

Please follow this link in PITS. It is logged for Silverlight but as we use single code-base you can refer to this issue no matter that it is not for WPF.
