Sorry for the repost, but I'm still struggling with this.
I'm trying to replicate a plot like this:

In this case, the yaxis on the left (the black dots) is linear
and the yaxis on the right (red data) is log base 2.
I can't figure out how to do the following:
1. How do I display the righthand yaxis so that is includes the
range above 32 and below 0 (as in the linked figure)? When I try to
include 0 or below in the
axis range, I get a range error (because of the log function). When I
do autorange, it ranges from 2 to 32. But I want to include 0 (and
below) in my figure.
2. How do I line up the centers of both axes. in this case, the yaxis
on the left needs to have the 0 value lined up with the value of 2 on
the y axis on the right. In other words, how to I move one yaxis
relative to the other.
This is the best I can do so far.

As you can see, I can't get the right axis as log2 and still keep the
0 values. I'd really like to have a log axis on the right, because
some of those values (red) are quite high.
Thanks for the advice.
