I have my own DataSource object, similar to Geojson DataSource object.
In it is a PointGraphics object whose default color is blue, I have a UI that allows the user to apply a red/yellow/green threshold based on data associated data. Both the fill and outline colors of the point get updated. Then I call dataSource.changedEvent.raiseEvent(dataSource);
This used to update the point(s) on the map in previous versions of Cesium. Any clue in what I need to do to fix it?
