Thans for your response! I have my data in four series,
three to be charted on the primary x-axis and one to be
charted on the secondary x-axis.

After a certain amount of experimenting, I found that I
can select the one series to be charted on the secondary
axis, then I must go to the Chart Options menu and
select "Secondary X-axis" and deselect "Secondary Y-axis".
The data charted correctly. I just had to follow it
through a bit more!

Ahh yes. I would have needed quite a bit more info to detect that one!
Good thing you found it yourself.
