Cumulative Cash Flow Curve?

Dear All;

How could I generate the Report of "Cumulative Cash Flow Curve"? Generating of this report for both early and late dates at the same time as a Graphic is easy.

I want to generate this report in CSV, WK1 or WKS format then to create better graphical "Cumulative Cash Flow Curve" presantation reports in excel.

If I am not mistaken I have read the previous postings but I could not manage to find a solution for my concern.

Thanks
