Help for Paretto's Curve

[Elton Freitas]

Hi people!!

I need help for development in programming for data inputs and create a Pareto Curve.
Example:
I will like input with "demand year" and "Cost" in the spreadsheet in the end final printed graphical curve.

item P1 P2 P3 P4 P5 P6 P7 P8 P9 P10 P11

Demand 1 2 3 4 5 6 7 8 9 10 11

Cost 10 20 30 40 50 60 80 90 10 11 12

Datas only example!

Thanks

Are you aware there is a pareto graph in statistics 1 var? How is that different from what you just linked to?

[Elton Freitas]

Yes, but I need to multiply "cost" and "price", after arranging for the highest value and generate the chart Pareto curve by dividing the classes A, B, C.
X axis => Elements and y-axis => Cumulative Percentage.
