How do I create a report showing total deals value £'s closed by the week during the month of Nov

I need to create a graph that illustrates total value of “closed - won” deals per week in any given month.

How do I do this?

Thanks.

I think I have answered my question…

Created a graph with close date and deal stage as filters. Then displyed these, measured by currency total, and selected frequency to be weekly and hey presto…
