When neither Performance Center, nor Alaysis are able to create graphs and the error message is:
"The following graph(s) were not created:
1. Hits per Second
3. Transaction Summary
4. Average Transaction Response Time
The graph, as defined, results in no data."
It can be useful to enable Transactions from the Options => Analyze Transaction Settings and also to select Summary Data Only in the Options => Result Collection. Additionally, please specify a Time Range in the same Options panel.
Note that the error message can state any graphs, not just the above and not in that order.
I hope this helps.
