How to display in the table only those requests for service that really were?

Hi everyone!

How to display in the table only those requests for service that really were.

I know that Grafana takes data from prometheus every 15-20 seconds and shows the changes in the table.

I need to change data in the table only when a real request is sent to the service from the client and in the table graphane appeared a new line with this field.

Now graphane shows the last request which was sent every 15 seconds, if there is no new one.

I want them not to be shown. And only new real requests will be added
