Grafana define Title value

I am trying to create a dashboard. Able to generate Bar Gauge from the Prometheus data for simple query sum by (namespace) (kube_pod_container_status_running)

I want to display only Namespace rather than {namespace="kube-system"}, so was playing with Visualization > Field > Title for a while, but was not able to figure out.

Any Idea How can just display kube-system instead of {namespace="kube-system"} and make the list in sorted order, because everytime when i refresh the dashboard, it reshuffles the order.

What I need here ?
