    Namespace: DevExpress.Xpf.TreeMap

    Assembly: DevExpress.Xpf.TreeMap.v25.1.dll

    NuGet Package: DevExpress.Wpf.TreeMap

    Declaration

    public string LegendItemPattern { get; set; }

    Property Value

    Type Description
    String

    A string that formats legend item text.

    Remarks

    Patterns can contain regular text (displayed as is) and value placeholders in braces. To format numeric and date/time values, you can apply format specifiers. Use a colon to separate a placeholder and its format specifier.

    The following table contains the available placeholders:

    Placeholder Description
    {L} Displays the group name.
    {V} Displays the total value of group items.
    {V1} Displays the first value of the range for a SunburstRangeColorizer.
    {V2} Displays the second value of the range for a SunburstRangeColorizer.

    If a pattern starts with a placeholder in the XAML markup, insert empty brackets into the beginning of the pattern as follows: “{}{L}: {V}”. For more information, refer to the following topic: {} Escape sequence / markup extension.
