Coordinate graph

Good morning everyone.

I am trying to build a Coordinate graph where I input my (date, item, x value, y value) in my table and excel will plot it on my coordinate chart. I don't know if a code has to be done or a formula, could someone help? Or if someone knows where I could find a spreadsheet that would do basically do what I am trying to do. This is nothing special just trying to plot them weekly and see a pattern.

Please feel free to change or add something I may have not added or overlooked.

Thank you for your time,
Brian
