I am trying to use charts from the WPF Toolkit (with LineSeries) and I don't want a legend at all. I need this since I have 10 such charts each with data from a different source and I would like to draw one legend for all 10, to save screen real estate.
By default the legend appears the moment you add a second LineSeries. Is there any way to prevent it from even appearing?
Thanks,
sprite.
There doesn't seem to be an especially clean way. One simple approach is to set the Legend's Width to zero using LegendStyle:
<charting:Chart>
<charting:Chart.LegendStyle>
<Style TargetType="datavis:Legend">
<Setter Property="Width" Value="0" />
</Style>
</charting:Chart.LegendStyle>
A more drastic approach is to replace the ControlTemplate with one that does not include a Legend:
<charting:Chart>
<charting:Chart.Template>
<ControlTemplate TargetType="{x:Type charting:Chart}">
<Border Background="{TemplateBinding Background}" BorderBrush="{TemplateBinding BorderBrush}" BorderThickness="{TemplateBinding BorderThickness}" Padding="{TemplateBinding Padding}">
<Grid>
<Grid.RowDefinitions>
<RowDefinition Height="Auto" />
<RowDefinition Height="*" />
</Grid.RowDefinitions>
<datavis:Title Content="{TemplateBinding Title}" Style="{TemplateBinding TitleStyle}" />
<chartingprimitives:EdgePanel Name="ChartArea" Style="{TemplateBinding ChartAreaStyle}" Grid.Row="1" Margin="0,15,0,15">
<Grid Panel.ZIndex="-1" Style="{TemplateBinding PlotAreaStyle}" />
<Border Panel.ZIndex="10" BorderBrush="#FF919191" BorderThickness="1" />
</chartingprimitives:EdgePanel>
</Grid>
</Border>
</ControlTemplate>
</charting:Chart.Template>
Use following namespaces:
xmlns:charting="clr-namespace:System.Windows.Controls.DataVisualization.Charting;assembly=System.Windows.Controls.DataVisualization.Toolkit"
xmlns:datavis="clr-namespace:System.Windows.Controls.DataVisualization;assembly=System.Windows.Controls.DataVisualization.Toolkit"
xmlns:chartingprimitives="clr-namespace:System.Windows.Controls.DataVisualization.Charting.Primitives;assembly=System.Windows.Controls.DataVisualization.Toolkit"
