How to have this graph?

HI! How can I do to have a graph which similar to this graph ?

I'm using LoadRunner 8.1. Mercury LoadRunner Analyse only produce graphs which show response time vs time, a vs time, b vs time,....

Thanks!

Hello, this can be done by merging the average response times and the running vusers graph.
1)open the analysis session in analysis
2)click on the average transaction response time graph
3)right-click in the graph and choose "merge graph"
4)choose "running vusers" from the list of options.
5)click OK

I hope this works!

I can't create a scenario to have number of Vusers which increase step by step
This is scenario schedule

Run scenario and get a result.

With WAPT,I can create the graph which I want but WAPT doesn't support to create script in comparision with LoadRunner,

To have the graph, LoadRunner must
- start 2 Vusers at the same time, wait until Vuser stop(finished their jobs), LoadRunner start measuring metrics(response time,...)
- start 4 Vusers at the same time, wait until Vuser stop(finished their jobs), LoadRunner start measuring metrics(response time,...)
- start 6 Vusers at the same time, wait until Vuser stop(finished their jobs), LoadRunner start measuring metrics(response time,...)
- start 8 Vusers, etc......

Oh!
Actually, I knowed about "merge graph" but I still have not used a option which can solve my problem :D
Heheheheh! Choose "Correlate" instead of "Overlay"
