LabelAngle QML Type

Specifies how to calculate the angular position and layout direction for labels on or around point feature symbols. More...

Import Statement: import Esri.ArcGISRuntime 100.11
Since: Esri.ArcGISRuntime 100.11




Detailed Description

The angular position may be different for each feature (driven by one or more feature attributes) or constant for all features (specified by a fixed number).

This QML type supports the following default properties. A default property may be declared inside another declared object without being assigned explicitly to a property.

TypeDefault Property

See also JsonSerializable.

Property Documentation

[default] angleExpression : ArcadeExpression

Specifies how the angle (in degrees) is calculated from the feature attributes, using an Arcade expression.

The calculation may use attributes, fixed numbers, or a combination of both. The default value is an ArcadeExpression containing an empty expression string, which will produce a zero angle when evaluated.

json : jsobject

JSON data that can be used to instantiate the LabelAngle.

rotationType : Enums.LabelAngleRotationType

Whether the angle should be interpreted as arithmetic or geographic.

The default value is Enums.LabelAngleRotationTypeAutomatic (which will be interpreted as Enums.LabelAngleRotationTypeArithmetic).
