When symbols have an offset from their position, it's important to still see what the real location is. This can be achieved with callouts:

symbol3D-line-callout

Callouts are graphics that help users understand where a label or a symbol (usually a point) is located on the map, when the symbols have an offset from their initial position.

Callout3D is the base class for classes that add a callout visualization when a PointSymbol3D or a LabelSymbol3D has an offset (for example a PointSymbol3D.verticalOffset). Currently only callouts of type line are supported. See LineCallout3D.

fromJSON

inheritedstatic Method

Signature: fromJSON (json: any): any

Inherited from: JSONSupportMixin

Creates a new instance of this class and initializes it with values from a JSON object generated from an ArcGIS product. The object passed into the input json parameter often comes from a response to a query operation in the REST API or a toJSON() method from another ArcGIS product. See the Using fromJSON() topic in the Guide for details and examples of when and how to use this function.

Parameters

Parameter	Type	Description	Required
json	`any`	A JSON representation of the instance in the ArcGIS format. See the ArcGIS REST API documentation for examples of the structure of various input JSON objects.

Returns: any
Returns a new instance of this class.

clone

Method

Signature: clone (): Callout3D

Creates a deep clone of the callout.

Returns: Callout3D
A deep clone of the object that invoked this method.

toJSON

inherited Method

Signature: toJSON (): any

Inherited from: JSONSupportMixin

Converts an instance of this class to its ArcGIS portal JSON representation. See the Using fromJSON() guide topic for more information.

Returns: any
The ArcGIS portal JSON representation of an instance of this class.
