Currently only whole test summarized TPS graph are provided in nGrinder. However The Grinder supports multiple tests in a single script like...
test1 = Test(1, "Test1")
request1 = test1.wrap(HTTPRequest())
test2 = Test(2, "Test2")
request2 = test2.wrap(HTTPRequest())
test3 = Test(3, "Test3")
request3 = test3.wrap(HTTPRequest())
test4 = Test(4, "Test4")
request4 = test4.wrap(HTTPRequest())
test5 = Test(5, "Test5")
request5 = test5.wrap(HTTPRequest())
Those are visible in the running page. but.. it's not in the detailed report page.
jqplot support multiple series on a single graph.
Please make Not only total TPS but also individual TPS wih legends visible.
Only TPS graph is enough. Do not consider other graph.
