Like an overcooked steak, reporting can be dry, bland, and not particularly easy to digest. A typical example delivers the goods in a simple table and shows trends as a percentage change from the previous month or year.
"Sparklines" to the rescue! Edward Tufte describes sparklines as:
"data-intense, design-simple, word-sized graphics." Whereas the typical chart is designed to show as much data as possible, and is set off from the flow of text, sparklines are intended to be succinct, memorable, and located precisely where appropriate.

Now with a quick scan, you can get a sense for the trend over the last 12 months. Bringing Sparklines from concept to reality is a Excel add-in put together by Andreas Flockermann of BonaVista Systems.

I spent a little time playing with his beta version and found it fairly intuitive. There is a chart format dialog box that helps you set various dimension including scale, colors, and reference lines.

Andreas says he started his new company to "help users to create better, richer reports with more information per square inch than integrates well into Microsoft technology." It is a worthy goal.
