I might be tempted to do this as a waterfall chart instead of a line
chart. A floating column shows the amount of difference between before
and after. You can put custom labels into the floating columns to show
percentages.

I have 5 sets of data, each with a before and after amount that has been
charted using a simple bar chart. Is it possible to have excel, using a line
from the before element to the after element, show the % change between the
two?

I can easily calculate the percent change between the two, but if I graph it
and set it to a line, the only way it can be seen is if I chart it on an
alternate axis. Further, I just want a line from the top of the before
element to the top of the after element, and a label showing the % change.

Confused? Hope not :)
Thanks for any help!
