As per your need , I have changed the ControlTemplate of the Legend a litte as shown below
<ControlTemplate x:Key="LegendControlTemplate1"
TargetType="{x:Type visualizationToolkit:Legend}">
<Border BorderBrush="{TemplateBinding BorderBrush}"
BorderThickness="{TemplateBinding BorderThickness}"
Background="{TemplateBinding Background}"
Padding="2">
<Grid>
<Grid.RowDefinitions>
<RowDefinition Height="Auto" />
<RowDefinition />
</Grid.RowDefinitions>
<visualizationToolkit:Title x:Name="HeaderContent"
ContentTemplate="{TemplateBinding HeaderTemplate}"
Content="{TemplateBinding Header}"
Grid.Row="0"
Style="{TemplateBinding TitleStyle}" />
<ScrollViewer BorderThickness="0"
IsTabStop="False"
Padding="0"
Grid.Row="1"
VerticalScrollBarVisibility="Auto">
<!--<ItemsPresenter x:Name="Items"
Margin="10,0,10,10" >
</ItemsPresenter>-->
<ItemsControl x:Name="Items"
Margin="10,0,10,10"
ItemsSource="{TemplateBinding ItemsSource}">
<ItemsControl.ItemsPanel>
<ItemsPanelTemplate>
<UniformGrid Columns="2" />
</ItemsPanelTemplate>
</ItemsControl.ItemsPanel>
</ItemsControl>
</ScrollViewer>
</Grid>
</Border>
</ControlTemplate>
I am not sure whether this suites your requirement or not..Please mark it as answer if satisfied.
