Overlay Plots via a list dialog

I currently have a list dialog where it asks the user for the computation method out of 4 choices and does some computation. Afterward, I have another list dialog where it asks the user which plots from the methods they chose would they like to overlay. I don't know how to write a code that depending on the user choice that it can dynamically add code to the plot() section of the figure syntax. I don't want to write 15 if statements with unique figure statements to check for every combination.
