I'm trying to create a report to show my sales matrics. My structure of the pipeline is:

LEAD ->CONTACT -> POTENTIAL-> SALE

The problem is that the reports only allows to put data from the module LEAD or the module CONTACT & POTENTIAL but not from both at the same time. There is a way I can get a single report with a funnel of conversion that includes the number of LEADS, number of CONTACTS and NUMBER of POTENTIALS?

The other thing I want to be able to report is a graph with the AXIS X per number of  (LEADS, CONTACTS, POTENTIALS, SALES) and the AXIS Y per week. How can I do it?

thanks
