RotationVariable Class
The rotation visual variable, determined by mapping the values to data in a field or
by other arithmetic means with an Arcade expression, controls how features rendered with
marker symbols or text symbols in a MapView ,
as well as with marker symbols, ObjectSymbol3DLayer or IconSymbol3DLayer in a SceneView,
are rotated.

Constructors
RotationVariable() Constructor
Parameterless constructor for use as a Razor Component.
public RotationVariable();
RotationVariable(string, Nullable, Nullable, VisualVariableLegendOptions, string, string) Constructor
Constructor for use in C# code. Use named parameters (e.g., item1: value1, item2: value2) to set properties in any order.
public RotationVariable(string field, System.Nullable<dymaptic.GeoBlazor.Core.Enums.Axis> axis=null, System.Nullable<dymaptic.GeoBlazor.Core.Enums.RotationType> rotationType=null, dymaptic.GeoBlazor.Core.Components.VisualVariableLegendOptions? legendOptions=null, string? valueExpression=null, string? valueExpressionTitle=null);
Parameters
field System.String
The name of the numeric attribute field that contains the data
values used to determine the color/opacity/size/rotation of each feature.
