>I would like to plot 2 different functions in one Plot. Is there any possibility to add a second y-axis (with a different range) so that one of the curves is related to this additional axis?

======

One way is to use Show with FullGraphics, e.g.

Here are two plots:

In[70]:= gr1 = Plot[x, {x, 0, 4 }]
In[74]:= gr2 = Plot[x^2, {x, 0, 4}, AxesOrigin -> {4, 0}]

Now show them together:

In[79]:= Show[{FullGraphics[gr2], FullGraphics[gr1]}]

As far as I know, if you want to scale things so that the ''length'' of each axis is the same (to the eye), you must do that ''manually'', e.g. in the plot below I multiply the first function plotted by a scale factor and create scaled Ticks.

In[85]:= gr1 = Plot[4 x, {x, 0, 4 },
Ticks -> {Automatic, Table[{i, i/4}, {i, 0, 16, 4}]},
PlotRange -> {0, 16}]

This is the ''scaled'' pair of plots.

In[86]:= Show[{FullGraphics[gr2], FullGraphics[gr1]}, PlotRange -> All]
