Arcade function to show unique values (remove duplicate values)
When using the Table Attribute dynamic text function in ArcGIS Pro you can return a string of values visible in the map frame (i.e.1, 2, 3, 4,...). Sometimes you may have a dataset with multiple features with the same value (i.e.1, 2, 2, 2, 3, 3, 4,...).. By using this function in it's current format, you would see the results as per the example given, but sometimes you may want to only see Unique values (i.e. 1, 2, 2, 2, 3, 3, 4 would be returned as 1, 2, 3, 4). It would be good if there was an Arcade function that shows unique values, removing any duplicates (suggestion below).
This post is another example of where this function would be useful: https://community.esri.com/t5/arcgis-pro-questions/how-to-remove-duplicate-values-from-dynamic-text-...
