[Observium] Graph aggregation on Observium guideline

Hi All,

Since I am new to Observium and I'm not quite sure if we can do like a graph aggregation like Cacti does on Group feature in Observium?

Just like on Cacti, we can do a graph aggregation on different nodes/hosts and I try to look around on Group features on Observium and still not found the way yet.

If it is possible, can anyone share me the guideline pls?

Thanks so much for your help.
