What is a situation in which you might locate points on a coordinate grid?

Imagine you are a company owner, you make hats. And each of your employees make different amounts of hats, so you can plot in a grid, the employee (give her a number) and the amount of hats she makes. Then you can plot the employee number in the x axis and the amount of hats she makes in the y axis, so yo can locate in a coordinate grid, how much each employee does.
