Thanks, i also found the xy switch add-on which moved my depth data to the
y-axis and then everything was fixed when i did what you suggested below.

Thanks

Make your XY chart with both sets of data. Double click one series, and on
the Axis tab, select Secondary. Excel helpfully gives you a secondary Y
axis, but only the primary X axis. Select Chart Options from the Chart menu,
and on the Axes tab, uncheck the secondary Y box, and check the secondary X
box.

I need to have two x-axis with two different types of data (ex: oxygen and
temp, one on top, one on the bottom) with one y-axis (depth, on the left).
The same basic concept as having 2 y-axes but with the x-axes.
