I have a feature layer published from an SDE feature class to a feature service via ArcGIS Enterprise, displayed in a web map and embedded in an ArcGIS Dashboard. The layer uses a proportional size renderer based on an Area field combined with unique value colours based on financial year.
Certain point features are not rendering at certain map extents, but become visible when zooming in or out. The behaviour is consistent — the same features always appear/disappear at the same extents. See the attached screenshots containing test data which demonstrates that at different extents, different points show. It seems that the same points disappear at the same extents.
What I've ruled out:
- It is not a record count issue — REST query confirms all 2796 features are returned regardless of extent
- It is not a browser cache issue — clearing Chrome cache makes no difference
- It is not the dual symbology — switching to a single proportional size renderer and location only renderer produces the same behaviour
- It is not a minScale/maxScale setting — adjusting these made no difference
- It is not a minimum symbol size issue — increasing minSize made no difference
- It is not environment-specific — the same issue occurs in both our DEV and TEST environments
- No errors appear in the browser console or ArcGIS Server logs
When I am zoomed out I get an error saying that the layer has not drawn properly due to the quantity of features. However, I would have thought that after I filtered in the web map that this issue would not occur, but I am wondering if the sane behaviour is occurring due to the number of data points in the service despite filtering - can anyone confirm and/or share any insight on why this might be occurring or you're experience in working around this.
Thanks in advance!
