There are probably ways to do this in regular Mathematica. One possibility
is to make two plots and align them in a Column. Leave the x-scale off the
top plot. Each plot would have its own y scale. The problem might be to get
the correct horizontal alignment of the two plots. It the top plot has
longer tick labels you may need to specify ImagePadding for both plots so
they take the same space.

You may get other suggestions.

What I would do is use the Presentations package ($50) from my web site.
There are two approaches I might use.

1) Put both functions in the same plot with an underlying y coordinate (0 to
10 say) but use Rescale to adjust the space taken by each function. I assume
that the lower function might be magnified in its y coordinate. Then I would
use the CustomTicks command in the package to put the lower tick scale on
the left and the upper tick scale on the left. These could be specified so
they only gave tick marks in the appropriate y region for each function.

2) A second method is a little like what I described above. I would use
Inset to place two plots on the same "piece of paper" without using any tick
scales. That makes it easy to align them. Then I would use the package
functions XTickLine and YTickLine to put tick labels on the edges of the
Insets. That way, we could get both tick scales on the left.

Hello,
I would like to plot two functions on the same 2-D plot. One function
has low values of y and the other has high values of y, so the figure
is rather ugly. How can I crunch the axis with a zig-zag to condense
the figure?
Thank you,
David
