Can Excel chart datapoints without you having to make a full chart?

Im in the process of doing a break even analysis for a buisness which has a formula:

BEP = TFC / (SUP - VCUP)
BEP Break Even Point
TFC Total Fixed Costs
SUP Variable Costs per unit of production
VCUP Selling price of unit

Since I dont need a chart to figure out the break even point Id rather not have a full table full of data points if I dont have to is there a way to get excel to just extrapolate the data and give me a chart, if not thats fine I can always just make a table, I just would rather not

Thanks.

As far as I know Excel only plots on a chart what it reads on the sheet itself. No data, no chart. But a line chart easily intrapolates between two points, so you don't need a full table full of data points, you just need one data point before your break even and one after your break even. If you don't understand what I mean, upload an example and I will show you.
