No, not if you:
1)Have "multi" definitions for the graph you want
2)You specify multiple server names in the graph url, or use the 
Reports->Metrics Report feature. I prefer adding the server names in the 
graph url, as I can reload it to have it update (whereas using the Metrics 
Report requires you to go back and select a new date range).

You may want to try this with one of the existing tests that has "multi" 
support, mem, cpu have them by default.
