Webinar: Heat Map Analysis

Presented by: Brent Weichers

Date: July 20, 2022 2:00 PM CDT

A heat map is a data visualization technique that shows the magnitude of action as color in two and three dimensions. The variation in color may be by hue or intensity, giving obvious visual cues to the reader about how the actions are clustered or vary over space. In a cluster heat map, which we will be reviewing, magnitudes are laid out into a matrix of fixed cell size whose rows and columns are discrete phenomena and categories, and the sorting of rows and columns is intentional and somewhat arbitrary, with the goal of suggesting clusters or portraying them as discovered via statistical analysis.

"Heat map" is a relatively new term, but the practice of shading matrices has existed for over a century. We will review a heat map being used to find the picking location activity in a warehouse and look at two examples of a heat map being used to make improvements.
