Is there a way to make a chart that compares the two same months of
different years worth of data?

For example, my spreadsheet has the date starting with January 2007 -
June 2008 as the header listed in order. I have some charts built off
of that but would like a bar chart that also lets me compare Jan 07
next to Jan 08, Feb 07 next to Feb 08, and so on.

Any ideas?
