I currently have two charts with different scales that i
would like to superimpose onto one another in order to
make one chart that compares both data sets. How can this
be done? Is it possible to create a single chart with
both data sets and then stretch a section of it (for
example: 1-10% on the y-axis is larger than 10-20%)?

thanks.

go to John Peltier's website with this link:
http://www.geocities.com/jonpeltier/Excel/index.html He has lots of great
info for combination charts and other stuff. If it is possible, he probably
has it. I only wish I could open the site myself. I apparently have some
faulty settings in my browser. Everybody else says it is working fine,
though, so you should have no problem.

Elizabeth,

Though i'm not completely sure that this will accomplish what you need, you
can give the "Secondary Y-Axis" a try.
Right click the series (ie 10 to 20 %)
Choose "Format Data Series . . ."
Under the Axis tab set "Plot series on" to "Secondary Axis"

I can think of a couple of different alternatives.

One, as already suggested, is to use a secondary axis. Dan E gives
directions for that in his response.

Another option is a logarithmic y-axis. Then the 1-10% range will the same
size as the 10-100% range.

A third option might be the broken y axis. That is not a native feature of
Excel, but Tushar Mehta shows you how to do it at his web
site.(www.tushar-mehta.com, Broken Y Axis).

Finally, you might try arbitrary axis labeling as described on Jon Peltier's
site
(http://www.geocities.com/jonpeltier/Excel/Charts/ArbitraryGridlines.html).

You have lots of options. I hope you find one that you like.
