%SPARKY: A SAS® Macro for Creating Excel Sparklines
Think big? No, think small! Characterized by their small size and high data density, sparklines are information graphics that present trends and variations associated with data in a simple and condensed way. This paper describes %SPARKY, a SAS® macro that creates cell-sized sparklines for embedding in Excel worksheets. This technique might be of interest to all skill levels. It uses Base SAS®, SAS/GRAPH®, the SAS® Macro Facility, Excel, and Visual Basic for Applications (VBA) on the PC platform.
