Microsoft likes to make a big deal about SparkLines, in Excel 2010. I've tried out the feature, but don't really have a use for them. Does anyone else, out there, use them for anything?
I've been using SparkLines in both Excel 2003 and Excel 2010. They are convenient when I have 4 streams of data that all have similar values across a line chart. The SparkLine will show me each stream's values in a line chart not mixed with the others, so I can see the up and down values over time.
The problem that I have with Excel 2010's SparkLines is that it will not give me an average value. The add-in that I use will allow me to show the average value over time as a line down the center of each SparkLine, so I can see where the data points are at, below, or above the average.
Obviously I'm only using the line chart style SparkLine and not the other types.
