1. I have a point layer created from a view table (Latitude / Longitude). I can see the layer when symbolised as a single symbol, or graduated symbols (quantities) when the co-ordinate reference system is GCS_WGS_1984. However, when I use a projected co-ordinate system I cannot see the layer anymore.
2. If the map is published using the GCS_WGS_1984 co-ordinate system, I cannot see the graduated symbolised layers when the the mapservice is accessed through ArcGIS online. However, if I access the same layers as individual feature layers, it is visible.
3. Although the symbols are not visible, the identify function, legend and attribute tables all works in ArcMap, ArcGIS online and through ArcGIS JavaScript API.
