I have a feature class of bicycle and pedestrian count locations and a table of count records from various years that is related to the feature class. That is managed in a (1-M) relationship class in the geodatabase. The map service is created from that data. I can display the related records in an ArcGIS Online map just fine. But I want to add a bar or column chart within the location popup that shows the count volumes for each year - the bike count total for each related record. There are options in the popup media configuration to create charts based on related records but when i try to create one, it ends up making my popup display nothing at all. Does ArcGIS Online support popup media for 1-M relationships? Am I doing something wrong or should I report his as a bug?
