Overlay CPU usage of multiple VMs on the same graph?

I've been clicking around the vSphere Client for a while now and can't seem to find a way of showing metrics from multiple VMs on the same graph

I can show many metrics from the one VM, or many metrics from many hosts, but not metrics from VMs on separate hosts.

I have a number of hosts, and the VMs I'm interested in are spread across those hosts. I'd like to see the CPU usage of the VMs on the same graph if possible (about 8 VMs in total)

Any suggestions? Image may be NSFW.
