With the Presentations package it is very easy to put any scales on any of the axes. The only requirement is that there must be a 1-1 mapping between the scale and the underlying plot coordinate. You can also completely control the tick values and format. Here is the example from the html link. (Putting the x^3 scale on the right is much better than the other way around.) Needs["Presentations`Master`"] f1[x_] := x^3; f2[x_] := Sqrt[x]; yrightticks = CustomTicks[#/35 &, {0, 70, 10, 5}, CTNumberFunction -> (Style[#, FontColor -> Red] &)]; yleftticks = CustomTicks[Identity, {0, 2, .5, 5}]; Draw2D[ {Red, Draw[f1[x]/35, {x, 0, 4}], Black, Draw[f2[x], {x, 0, 4}]}, Frame -> True, FrameLabel -> {{f2[x], f1[x]}, {x, None}}, RotateLabel -> False, FrameTicks -> {{yleftticks, yrightticks}, {Automatic, Automatic}}, PlotLabel -> "Plotting Two Functions with Different Scales", ImageSize -> 500] -- David Park djmpark at comcast.net http://home.comcast.net/~djmpark/ <avteran1 at gmail.com> wrote in message news:g9t6of$ja8$1 at smc.vnet.net... > Hello All, > > In my efforts to create a two-axis graph in Mathematica v6.
