# Interface TemporalRendererJson

A temporal renderer is used to perform time-based rendering of features in a feature layer.

See https://developers.arcgis.com/web-map-specification/objects/temporalRenderer/.

interface TemporalRendererJson {
authoringInfo?: AuthoringInfoJson;
latestObservationRenderer?: SimpleRendererJson;
observationalRenderer?: SimpleRendererJson;
rotationExpression?: string;
rotationType?: RotationJsonType;
trackRenderer?: SimpleRendererJson;
type: "temporal";
visualVariables?: VisualVariableJson[];

Properties

### `Optional` authoringInfo

authoringInfo?: AuthoringInfoJson

An object containing metadata about the authoring process for creating a renderer object. This allows the authoring clients to save specific overridable settings so that next time it is accessed via the UI, their selections are remembered. Non-authoring clients should ignore it.

Inherited from RendererJsonBase.authoringInfo

### `Optional` latestObservationRenderer

latestObservationRenderer?: SimpleRendererJson

Simple renderer used to symbolize point geometries for the most current observations.

### `Optional` observationalRenderer

observationalRenderer?: SimpleRendererJson

Simple renderer used to symbolize regular/historic observations.

### `Optional` rotationExpression

rotationExpression?: string

A constant value or an expression that derives the angle of rotation based on a feature attribute value. When an attribute name is specified, it's enclosed in square brackets.

Inherited from RendererJsonBase.rotationExpression

### `Optional` rotationType

rotationType?: RotationJsonType

String value (either geographic or arithmetic) which controls the origin and direction of rotation on point features. If the rotationType is defined as 'arithmetic', the symbol is rotated from East in a counter-clockwise direction where East is the 0� axis. If the rotationType is defined as 'geographic', the symbol is rotated from North in a clockwise direction where North is the 0� axis.

Inherited from RendererJsonBase.rotationType

### `Optional` trackRenderer

trackRenderer?: SimpleRendererJson

Simple renderer used to symbolize the tracks.

### type

type

The type of renderer. See RendererJsonType.

Overrides RendererJsonBase.type

### `Optional` visualVariables

visualVariables?: VisualVariableJson[]

An array of visualVariable objects used for continuous color or size, simple, and unique values with feature opacity.
