[Solved] ItemLabels Appearance?

[Iurie Coroban]

Hi,

In Bar Chart I have situation, when the max value= 150 and the min value=1, ItemLabel for serie where YValue==1 is not visible.
It is possible to show ItemLabels text on the top outside the series, if yes how to do this?
Are you planed to implement Scale Breaks?

Thanks.

Hello Lurie ,

Currently, RadChart does not expose any property for  this and the only way you could do this is to use the SeriesItemLabelStyle property of the series definition to change the template of the label controls.
Here is a sample code:

//the namespace of the RadChart's controls
xmlns:t="clr-namespace:Telerik.Windows.Controls.Charting;assembly=Telerik.Windows.Controls.Charting"

//the style which is to be applied to the series item labels.
        <Style x:Name="labelStyle" TargetType="t:SeriesItemLabel" >
            <Setter Property="Template">
                <Setter.Value>
                    <ControlTemplate TargetType="t:SeriesItemLabel" >
                        <Canvas>
                            <TextBlock x:Name="PART_TextContainer"
                                        Canvas.Top="-20"
                                        Canvas.Left="{TemplateBinding TextContainerCanvasLeft}"
                                        VerticalAlignment="Stretch"
                                        TextAlignment="Center"
                                        FontSize="14"
                                        Text="{TemplateBinding Content}"
                                        Foreground="{TemplateBinding Foreground}"/>
                        </Canvas>
                    </ControlTemplate>
                </Setter.Value>
            </Setter>
        </Style>

//the series definition
SeriesDefinition d = new BarSeriesDefinition();
d.SeriesItemLabelStyle = this.FindName("labelStyle") as Style;

As for your second question - currently we have no plans to implement such functionality in the near future.

Hope this will help.

All the best,
