More details... I have two distributions which are very similar. I have plotted density plots already from the two distributions. In addition, I created a qqplot that show an almost straight line. What I want is a line that represents the ideal case in which the two distributions match perfectly. I would use this line to see how much the errors divert at different stages of the plot.
