Feature reduction popup
Since version: 1.15
In the feature reduction popup profile, map authors can write expressions that return values (i.e. attributes) for display in the popup of a clustering or binning visualization. Expressions can be referenced in the popup content's text template, field tables, and media charts. The expression executes when the popup displays. The script should return either text or a number and be referenced in the table cell or text comprising the popup's content.
The following products implement this profile:
- ArcGIS Pro
- ArcGIS Enterprise
- ArcGIS Online
- ArcGIS Maps SDKs for Native Apps
The spatial reference of the map in which
$feature is rendered determines the spatial reference of the expression's execution context.
|$feature||Feature||Provides access to the aggregate fields defined in either clustering or binning popups, such as |
|$aggregatedFeatures||FeatureSet||A FeatureSet containing all the features represented by the cluster or bin.|
