Below is a chart I have in Grafana:

My problem is that if my chosen time range is say 5 minutes, the graph wont show only what happened in the last 5 minutes. So in the picture, nothing happened in the past 5 minutes so it's just showing the last points it has. How can I change this so that it goes back to zero if nothing has changed? I'm using a Prometheus counter for this, if that is relevant.
