What is the best way to plot two curves with different Y axis scales? Such as Sin[x] and 2 Sin[x^2]+Cos[x] for example. One method is to rescale each individual curve (so that in the we would then have Sin[x] and 2/3 Sin[x^2]+Cos[x]/3 as a scaled function) and then write out the FrameTicks->{Automatic, {y1 ticks}, None, {y2 ticks}}, where y1 and y2 are an array of ticks. Is there a package that does that does something similar for Mathematica version 4.0? -Roger Jones
