Namespace: DevExpress.XamarinForms.Charts

Assembly: DevExpress.XamarinForms.Charts.dll

NuGet Package: DevExpress.XamarinForms.Charts

Declaration

public string TextPattern { get; set; }

Property Value

Type	Description
String	The text pattern.

Remarks

Use the TextPattern property to format series label text. The pattern comprises regular text (which is displayed as is) and placeholder strings enclosed in braces. Placeholders define which values are shown in labels.

Below is a list of available placeholders.

Placeholder	Description
{S}	Displays a series name.
{A}	Displays a series point argument.
{L}	Displays a pie series point label.
{V}	Displays a series point value.
{VP}	Displays a series point value as percentages.
{W}	Displays a Bubble series point weight.
{O}	Displays a financial series point open value.
{H}	Displays a financial series point high value.
{L}	Displays a financial series point low value.
{C}	Displays a financial series point close value.
{HV}	Displays a range bar series point max value.
{LV}	Displays a range bar series point min value.

Note

These values can be formatted using default format strings after the $ sign. For example, in the {VP$#.##} string, VP is a placeholder, $ is a format string separator, and #.## is a format string.

Example

This example demonstrates how to add labels to pie chart segments, customize the text pattern, layout and appearance of series labels.
