WPF移动文本“；“外部”；其自身元素的边界

我正在用ItemsControl创建一个LinearGauge控件。我想显示的边界标签正好在两个酒吧的中心。我将尝试在下面的屏幕截图中描述我的问题：

因此，标签都应该向右移动几个像素。但问题当然是，元素边界是下一个彩色条开始的地方。所以我想移动标签“同时忽略元素边界”

做那样的事有什么简单的诀窍吗

到目前为止，我拥有的xaml：

    <ItemsControl 
        Grid.Row="0"
        Grid.Column="0"
        ItemsSource="{Binding Elements}">
        <ItemsControl.Resources>
            <DataTemplate DataType="{x:Type local:HorizontalGaugeElement}">
                <Grid>
                    <Grid.RowDefinitions>
                        <RowDefinition Height="Auto"/>
                        <RowDefinition Height="Auto"/>
                    </Grid.RowDefinitions>
                    <Grid.ColumnDefinitions>
                        <ColumnDefinition Width="Auto"/>
                        <ColumnDefinition Width="*"/>
                        <ColumnDefinition Width="Auto"/>
                    </Grid.ColumnDefinitions>

                    <Rectangle 
                        Grid.Row="0" Grid.Column="0" Grid.ColumnSpan="3"
                        Height="30" 
                        Fill="{Binding Color}">
                        <Rectangle.Width>
                            <MultiBinding Converter="{StaticResource BoundsToWidthConverter}">
                                <Binding Path="Lower"/>
                                <Binding Path="Upper"/>
                                <Binding RelativeSource="{RelativeSource AncestorType={x:Type ItemsControl}}" Path="DataContext.ValueToPercentage"/>
                                <Binding RelativeSource="{RelativeSource AncestorType={x:Type ItemsControl}}" Path="DataContext.GaugeSize"/>
                            </MultiBinding>
                        </Rectangle.Width>
                    </Rectangle>
                    <TextBlock 
                        Visibility="{Binding ShowLowerBoundary, Converter={StaticResource BooleanToVisibilityConverter}}"
                        Grid.Row="1" Grid.Column="0" 
                        Text="{Binding Lower}"
                        Margin="5, 0, 0, 0">
                    </TextBlock>
                    <TextBlock 
                        Grid.Row="1" Grid.Column="2" 
                        Text="{Binding Upper}" TextAlignment="Right"
                        Margin="0, 0, 0, 0">
                    </TextBlock>
                </Grid>
            </DataTemplate>
            <DataTemplate DataType="{x:Type local:VerticalGaugeElement}">
                <!-- similar story but then vertical --> 
            </DataTemplate>
        </ItemsControl.Resources>

        <ItemsControl.ItemsPanel>
            <ItemsPanelTemplate>
                <StackPanel Orientation="{Binding IsHorizontal, Converter={StaticResource BoolToOrientationConverter}}"/>
            </ItemsPanelTemplate>
        </ItemsControl.ItemsPanel>

    </ItemsControl>

尝试负边距：

margin=“0,0，-5,0”

或rendertransform translatetransform。具有正X值。像一个符咒，thx@ash像一个符咒，thx@Andy:）。两者都很完美
