How can I draw total cost lines for multiple items with different optputs in one chart? Please note that some have fixed costs and some do not

when the demandoutput) is 10000
	output	Fixed costs	Variabe costs per unit	Total cost
Process 1	10000	$200,000	$16	$360,000
Process 2	10000	$240,000	$14	$380,000
Vendor A	10000	$0	$20	$200,000
Vendor B	10000	$0	$18	$180,000
Vendor C	10000	$0	$19	$190,000
when the demandoutput) is 60000
	output	Fixed costs	Variabe costs per unit	Total cost
Process 1	60000	$200,000	$16	$1,160,000
Process 2	60000	$240,000	$14	$1,080,000
Vendor A	60000	$0	$20	$1,200,000
Vendor B	60000	$0	$18	$1,080,000
Vendor C	60000	$0	$19	$1,140,000

The correct one is the following kind of chart, but I can't do it, If possible I would like to know the steps in excel. thank you!

Process 1-+ Process 2 Vendor A* Vendor B* Vendor C 2,500,000 2,000,000 1,500,000 TOTAL COST 1,000,000 500,000 0,0 0,0 20,000 40,000 60,000 80,000 100,000 120,000 VOLUME
