Report in Jmeter

[Dang Quoc Bao (FHO.FSB)]

Dear All!
In Jmeter, I know two glossarys that: requests/s and transactions/s.
Now, I'm creating a report(chart) in Jmeter. And I'm facing an issue that: "May 
I merge 2 lines(request/s and transaction/s) into the chart of report Or May I 
divide 2 lines (request/s and transaction/s) into 2 reports(Chart)"?
I hope someone will help me, please.
Thank  you very much.
