Grafana Graph Axes Mode SERIES

Hi, want create a Graph panel using the Axes Mode “SERIES”, to show about 20 nodes as a serie.
for each node i will see for example cpu_used and cpu_total cpu_free and maybe vms.
DS Prometheus, node exporter, openstack_node exporter.

I tried to use Graph Display Series Overrides, with out success.

  • Is this the right approach?
  • What to consider using Axes Mode “SERIES”?

I can’t find exampels, Some help would be nice, thanks in advance.
