Re: XY Graph question

Right click on the Y scale and select Duplicate Scale. You can keep it
on the left side or right click again on the scale you want and select
Swap Sides. When you have a duplicate scale, the next thing to do is
to associate that scale to a specific plot. In the plot legend, right
click the plot and select Y Scale. You should see both scales and
select the one you want to associate it with.
