This module provides a function for regenerating renderers based on the current state of the layer and view. This is useful when you want to update a renderer based on changes to the layer's data, the data visible in the view, binning configuration, or the view's scale.

Functions

regenerateRenderer

Function

Regenerates the renderer for a layer based on the current state of the layer and view.

Signature

Parameters
ParameterTypeDescriptionRequired
params

An object containing the following properties.

Returns
Promise<RendererUnion>

Returns a promise that resolves with the updated renderer.

Type definitions

layer

Property
Type
FeatureLikeLayerOrAdapter

The layer for which to regenerate the renderer.

view

Property
Type
MapViewOrSceneView

The view in which the layer is rendered.

renderer

Property
Type
RendererUnion | undefined

The renderer to update. If not provided, the renderer will be derived from the layer or feature reduction object.

forBinning

Property
Type
boolean | undefined

Indicates whether to regenerate the binning renderer or the renderer set on the layer.

filter

Property
Type
FeatureFilter | undefined

When defined, only features included in the filter are considered in the attribute and spatial statistics calculations when determining the final renderer. This is useful when a lot of variation exists in the data that could result in undesired data ranges. A common use case would be to set a filter that only includes features in the current extent of the view where the data is most likely to be viewed. Currently, only geometry filters with an intersects spatial relationship are supported. All other filter types (including where) are ignored. This parameter is only supported when forBinning is false.

includedParts

Property
Type
("color-variable" | "size-variable" | "class-breaks")[] | undefined
Since
ArcGIS Maps SDK for JavaScript 4.33

An array of strings indicating which parts of the renderer to include in the regeneration. If not provided, all parts are included by default. The available options are:

  • color-variable: Only regenerate the color visual variable.
  • size-variable: Only regenerate the size visual variable.
  • class-breaks: Regenerate the class breaks for the renderer.
