Ive added secondary y axes before, so you can have a series relating to the
left hand axis and one on the right, but with a common x axis

but is there an easy way to have two x axis, one at the top and one at the
bottom. i don't actually need a 2nd series, but I want my charts to have one
unit across the bottom (dose) and another along the top (exposure index)
just for reference, so that visually I can look at the curve and read off
either dose (at the bottom of the chart), or exposure (at the top)

thanks in advance

A simple way to do it is to plot your data twice. change the axis on one and
set line and sybol to none for one.
in input the two x lable sets

can you do that with x axes though? I've done it before with y axis but not
x axis

Sometimes you need to insist that Excel provide the secondary X axis.
When you assign a series to the secondary axis, Excel usually just
provides the secondary Y axis. You can go to Chart Options on the Chart
menu, and on the Axes tab, specify which primary and secondary axes you
want.

thanks Jon, I get that bit, but how is the 2nd x axis included in the chart?
If I add another series it has the same x axis as the 1st, so moving it onto
the secondary y axis won't help. To move it onto a secondary x axis, there
needs to be secondary x axis data, this is where I'm having trouble. If you
just add a series to a chart, and it has a different x axis it messes up the
whole chart. Or maybe I just need to do the chart options and it will refix
itself? I'll give it another go when I get in
cheers

If you assign the series to the secondary axis, then get the X axis
through the chart options dialog, both X axes will be the same. Now go
to Source Data (Chart menu), Series tab, and assign the proper X data
for the secondary axis series.
