clear graphics in stream layer Web App builder code

[Pa_Lotus]

Hi

I have a stream layer configured in web app builder.

data is related to ongoing trips tracking. stream layer only gets data related to active trips.

map is not clearing previous trips data(point)

can anyone suggest me where to clear the map graphics

Thanks
