I have tried >(possibly with incorrect syntax) the ImplicitPlot function >in the Graphics addon, but it chokes. If you want to plot what you call the resulting graph after a glide reflection, thus making x a function of y, you can use instead of ImplicitPlot a ParametricPlot, in which case I suggest in replacement to your very last line: Show[ParametricPlot[{#,current}, {current,0,1}]&/@transferFunctionList] Laussy.
