Can I enable the metric functionality for the Tempo data source in Grafana Demo?
I want to see the Service Graph in Grafana Demo.

There are no service graph metrics yet (at least not in the time frame you selected).
Did you already send traces to Tempo?
And does that have more then 1 service in the trace?

As soon as that is the case, then trace metrics are generated and that will be available here.
