Chart Symbology is available in ArcGIS Pro and ArcGIS Insights. Will this functionality be available in Map Viewer (ArcGIS Online/ArcGIS Enterprise) in the future?
Some users have the requirement to display polygons feature such as states boundaries using categories in ArcGIS Dashboards. However, this is not readily available in Map Viewer. The workaround is to duplicate the boundaries data for each of categories so that it can be filtered by ArcGIS Dashboards' selectors, which causes data redundancy.
I believe this should be doable as it is already available in Insights, which is a web app, and also web maps currently support creating charts in pop-ups, so it should be possible to do the same to the feature classes, correct?
