Override cluster symbol with UniqueValueRenderer

mute55 — Tue, 16 Mar 2021 17:43:30 GMT

Hi,

My application displays multiple types of features with differing symbols using a feature layer with a unique value renderer, like so

{ type: 'unique-value', valueExpression: `When($feature.type == 'someType', '1', $feature.type == 'someType', '2', $feature.type == 'someType', '3', '0')`, uniqueValueInfos: [{ value: '1', symbol: someSymbol, }, { value: '2', symbol: someSymbol, }, { value: '3', symbol: someSymbol, } ], }

This works very well, however upon adding a featureReductionCluster to the feature layer, the generated cluster symbols seem to be a random selection of of the features it represents, albeit a different size.

Removing the valueExpression and specifying defaultSymbol in the renderer gets around this, as the cluster symbol inherits the symbol/size from the default.

However due to the nature of my use case I am required to perform some advanced differentiation, requiring the use of valueExpression with an Arcade expression.

Is there a way to retain the use of valueExpression on a renderer and still have control over the cluster symbol?

Apparently there's an undocumented symbol property in FeatureReductionCluster - https://community.esri.com/t5/arcgis-api-for-javascript-ideas/arcgis-javascript-4-cluster-renderer/idc-p/1059638#M48
