There is another possibility that hasn't been mentioned: Draw two sets of axes in the same plot and then draw your curves relative to the appropriate set of axes. It's then easy to draw a line between points in the different reference systems. See < http://rowdy.mscd.edu/~talmanl/HTML/MovingSlopeTriangle.html> for an animation constructed in this way.
