I have a stream layer that shows my events in WebMap.
Now I want that the events that has alert will be shown in Red.
I did a filter and connect it to a different stream service and draw it in a different symbol.
The problem is that the last alert stay on screen.
For example even the car is far away and in low speed the last location of the alert of high speed still visible on screen.
What is the correct way to show this?
