Sparklines in Excel

I am veering off my normal course of Word postings and posting about Excel this week.  Specifically, I want to talk about sparklines.  When I think of sparklines, I see my 10-year old with his Razor Spark Scooter going down the driveway (after dark because what good are sparks in the daylight).  Sparklines in Excel are great during the day or at night!  So, what are sparklines?  Sparklines are small line charts embedded into the data you are describing.  This is a great link (with pictures) that show you exactly what sparklines are.  http://blogs.office.com/b/microsoft-excel/archive/2009/07/17/sparklines-in-excel.aspx  Instead of one large chart on your Excel worksheet, you can now have many smaller "charts" that will indicate the rise and fall of data over time.
