The Histogram-Area Connection

William Gratzer; James Carpenter 

December 2008, Volume 102, Issue 5, Page 336

Abstract:
An alternative approach to the construction of histograms is demonstrated—one based on the notion of using area to represent relative density in intervals of unequal length. The resulting histograms illustrate the connection between the area of the rectangles associated with particular outcomes and the relative frequency (probability) of those outcomes.
