Namespace: DevExpress.Xpf.Charts
Assembly: DevExpress.Xpf.Charts.v24.1.dll
NuGet Package: DevExpress.Wpf.Charts
Declaration
Property Value
| Type | Description |
|---|---|
| String | A String that specifies the label text pattern. The default value is String.Empty. |
Remarks
Use the LegendTextPattern property to define a text pattern for legend items. The LegendTextPattern contains text and placeholders enclosed in braces. Placeholders define values that should be shown in labels. The {A} - {V} pattern displays a series point argument and value in each label.
You can also use standard and custom format specifiers with placeholders and data field values. For example, the {V:F1} specifier shows point values with a single decimal digit.
When the chart is bound to data, the text pattern can contain data field values. For example, if the data source contains the Discount field, you can add this field to the pattern as follows: {S}: {V:F2} (Discount: {Discount:P0}).
The following tables list the placeholders that are available for the Chart Control and Chart3D Control:
