My Science fair topic/question is: Do homemade, natural cleaning products work just as well or better than store bought products that contain harsh chemicals?
My question is- how do I record the data and display it in a graph?

The purpose of doing your experiment is to prove/disprove your hypothesis. The best way to display your results will depend a lot on your hypothesis. If you provide your hypotheis and tell us a bit about your experiment and the data you collected (we don't need actual data, just a description of what data you collected) we might be able to answer your question.
