I'm doing a science fair project:http://www.sciencebuddies.org/science-fair-projects/project_ideas/Chem_p084.shtml?fave=no&isb=cmlkOjExNjUwMTc2LHNpZDoxLHA6Mg&from=TSW and my data/results have no numbers so how would I make a graph showing this? (P.S. my results are colors in order from brightest to least brightest: red, orange, green, etc.)

colours are part of the electromagnetic spectrum (or sections of it). So, you have a way of expressing them in terms of wavelength or frequency.
You can also evaluate them in terms of how bright they seem to different people - a juster scale type of approach, with the various colours given a value (like from 1 to 7) according to how bright people think the colour is compared to the others, and presented either as a scatter chart or a series of histograms or bar charts or even a pie chart.
It's up to you how you develop the numbers and the type of graph you want to use

I dont think so, and the reason is that a graph is actually a pictorial representation of a numerical analysis. Numbers then are the chief element in a graphical representation. They are the cause element in a graph, not the effect.
