I tried to to the calculation as per your email, but I still can't get it to
align both axes at 0.. Can you please let me know where I input the code you
provide on your website?

Thanks.

The primary X axis has no connection to the secondary Y axis. Del points out
correctly that you need to make sure the Y axis scale parameters are related
by their ratios. I have some VBA code on this web page that will align the
axes for you:

I'm trying to get the x axis to cross the y axis at zero for both the
primary
and secondary y axis. However, since both sets of data points has
negative
figures the x axis crosses the secondary y axis at a negative number.
What
am I doing wrong?

You must make sure the two Y axes have maximum and minimum set to the same
proportion with respect to their zeroes. So if the primary Y axis goes
from -5 minimum to +10 maximum, and the secondary Y axis must have a
maximum of +4, then set its minimum to be -2. And so on.
