Hi,
CP's will be the real solution in 9.1. Until then, you can use the Top X axis to substitute the Bottom axis.
Here is the procedure, though tedious, and of course, you cannot use the top X.
1) Open X Axis dialog ("Format: Axes: X Axis" menu)
2) Select Grid Lines tab.
3) For Vertical, at Additional Lines, turn OFF the "Y=0".
4) Select Title & Format tab.
5) For Bottom, at Major/Minor Ticks, select "none"
at Axis Position, select "At Position =", and set -100 (value you wanted).
6) Cut the string (typically "%(?X)") at Title.
change to Top, and paste this string to Title.
7) Also for Top, turn ON Show Axis & Ticks check box, and
at Axis Position, select "% From Top", and set -100 (%).
8) Select Tick Labels tab,
9) For Top, turn ON Show Major Labels.
10) For Bottom, turn OFF Show Major Labels.
11) Select Tick Custom Tick Labels tab,
12) For Top, set Vertical to e.g. -170 for the offset position.
13) Press OK.
14) Right-click the X axis title, select Programming Control fly-out,
and set 1 at "Link to (%, $), Substitution Level. Click OK.
Then, move the X axis title to the proper position.

P.S. If you need to make more than one graphs like this, I suggest you to make your own template after making the first one.
