AFTER you've done your research and concluded your experiments, it is time to prepare for the science fair. Ask specific questions about preparing for a science fair, including how to set up your display board, how to prepare a presentation, etc. (Please post questions about selecting a project or conducting your experiment by posting in the appropriate "area of science" forum.)

This project asks you to measure (1) the distance each dye component traveled up the chromatography paper and (2) the distance the solvent traveled. Did you make these measurements? These measurements have numbers associated with them (e.g., 5 centimeters). So, the measurements you made incorporate numbers into the project. Calculating Rf also uses numbers. As far as making a graph goes, one option would be to make a bar graph that shows the Rf value for each of the dye components.
All the best,
