In the recent Jan/Feb/Mar 2013 edition of the Visual Business Intelligence Newsletter, I introduced an extension of Tufte’s sparklines called bandlines. In less than two weeks since their introduction, without any prior knowledge of them, the software company XL Cubed has incorporated bandlines into their product. Here’s a screen shot of an example:
XL Cubed works as a companion to Excel. It can be used to extend Excel’s data visualization and analysis capabilities, including the addition of bullet graphs. You can read about this implementation in their recent blog post appropriately titled Bandlines in XL Cubed. This is not an endorsement of the product (I don’t give endorsements), but merely an announcement that one software company so far has recognized the value of bandlines and beat all others out of the gate.
