Grafana —> Cloudwatch

Hey Everyone,
Need your help please🙏
I integrate Grafana to pull data from Cloudwatch, and when I montior CPU Utilization and display all of my EC2 in a time series graph — all of them in the same panel, I can only see the instance ID… but I want to display the instance name as alias, I tried to create a dynamic variable, and when I do,
I see the instance names returned from the query…
but in the panel I couldn’t show them as alias.
Anyone has an idea?

Thanks in advance!
