The feature reduction cluster drawingInfo object contains drawing information, such as labelingInfo, for featureReduction (e.g. clustering) on a feature layer.
Referenced by: Feature Reduction Cluster
Properties
| Property | Details |
|---|---|
| labelingInfo[] | An object defining the properties used for labeling clusters. |
| renderer | An object defining the symbology of the cluster which provides the symbology for the layer. If not defined, web clients will infer a cluster style from the layer's renderer. Other clients may infer a style or set a default cluster style. If no visual variables are present in a simpleRenderer or a pieChartRenderer, then cluster sizes will automatically be rendered based on the clusterMinSize and clusterMaxSize. |
Clusters with labels. No defined renderer. Example

The client will size clusters based off clusterMinSize and clusterMaxSize.

}Clusters visualized with a simple renderer to override the cluster symbol and a color variable to color the cluster by count. Example
The client will size clusters based off clusterMinSize and clusterMaxSize because no size variable is present.

}Visualizes clusters based off the sum of an attribute. Example
The client will ignore clusterMinSize and clusterMaxSize in this scenario.

The client will use clusterMinSize and clusterMaxSize for the sizes in this scenario.
