Hello everyone, Say I have two plots, y=x^2 and y=2x, aligned vertically using GraphicsColumn. Their domains are aligned because x runs from -3 to +3 in both. I'd like to be able to draw a line from a point in the top graph to a point in the bottom graph. How can I do that? Regards, Gregory Hi, Gregory, Here is a minimalistic approach. Try it: pl1 = Plot[x^2, {x, -3, 3}]; pl2 = Plot[2 x, {x, -3, 3}]; Show[{GraphicsColumn[{pl1, pl2}], Graphics[{Red, Thick, Line[{Scaled[{0.6, 0.12}], Scaled[{0.6, 0.64}]}]}]}] Have fun, Alexei Alexei BOULBITCH, Dr., habil.
