I have a chart showing burn rates (fairly small numbers) and EACs/ETCs(Relly
big numbers). I have set up 2 Y-Axis, but this stretches the burn rate a
lot, so if it changes a little bit, it adjusts the axis and suddenly, a 1%
spike goes all the way from the bottom edge to the top. I know I can define
the axis to compensate, but then if there really were a spike, it has the
potential to go off the page, something I'm not sure people will know how to
fix when I leave this internship in a couple weks.

What I want to do is add another set of data, a percent change in the burn
rate. Obviously, I don't want to show this as another line, but rather as a
label on the burn rate data points. This should be really easy, but I can't
find a way to do it. Also, I'm pretty iffy about downloading things as this
is a government-owned computer.
