If you're willing to use macros, you can link the scales to each axis to
worksheet cells. Jon's site provides the code and shows how this can be
done.

Hi,

How can I create a link between values on primary and secondary Y-axis?
These values should not be set manually since there are many sheets and the
values will cahnge.

For example, if I want that the values of left Y-axis (from 0 to 200 and
from 0 to 500) are always the values of right Y-axis divided by 2 (from 0 to
400 and from 0 to 1000).
