Using Excel 2k3...

Ok, I have a basic set of data, detailing cash values by month, for a period
of several years. Here's what I'm working toward, but haven't been able to
get it to work.

I'd like to be able to group a series of values (for example, June of one
year through May of the next) on the chart as a SINGLE bar. As another
option, I'd like all bars of a single calendar year to be the same color,
even though they're different data elements...

Thoughts? Thanks!
Jack
