I'm trying to display a graph in the Requirement Module. I have created a button and associated code in the Script Editor. But when I click on the button nothing happened in QC. Can someone help me ?

Set myReqFactory = TDConnection.ReqFactory
Set myFilter = myReqFactory.Filter
myFilter("RQ_USER_02") = "zzz"
Set myGraph = myReqFactory.BuildSummaryGraph("RQ_REQ_NAME", "RQ_USER_02", , 0, myFilter, True, True)
