Hello Llaslo,

By default the text shown on the XamSegmentedDisplay is stretched. As far as alignment the ContentPresenter element's HorizontalAlignment can be set to Right. In each of the segments can be set to a fixed width with matching the number of characters using Digits from the Text property. E.g.:

<Style TargetType="local:XamSegmentedDisplay">
        <Setter Property="Background" Value="Black" />
        <Setter Property="TextForeground" Value="White" />
        <Setter Property="TextForegroundUnlit" Value="#25FFFFFF" />
        <Setter Property="Template">
            <Setter.Value>
                <ControlTemplate TargetType="local:XamSegmentedDisplay">
                    <Border Background="{TemplateBinding Background}">
                        <ContentPresenter x:Name="RootElement" HorizontalAlignment="Right"  />
                    </Border>
                </ControlTemplate>
            </Setter.Value>
        </Setter>
</Style>

<Style TargetType="local:SevenSegmentDigit">
        <Setter Property="Width" Value="15" />
</Style>

<ig:XamSegmentedDisplay SegmentMode="SevenSegment"
Digits="5" Text="ABCDE" Margin="0,0,0,15" Height="64" />

Let me know if I can provide any further assistance.
