Other techniques could be investigated : variation of grain (grey level), variation of size,
variation of shapes, etc. A classical study of these "retinal variables" is [3]. Bertin has shown
that the various techniques are not equally good for all kind of graphics :
(from Spence "Information Visualisation")
Variation of grey :
Here, we limit experimentations with 3 states only : nominal, low and high priority. A
simplified mockup, using grey levels with rectangular shapes and systematic antenna
numbering, can be derived from the actual chessboard. It suffers bad data/ink ratio because of
shapes boundaries :
Using a circle for individual status possibly lead to a compact view. Using a grey background
(grey200) enhances contrast. A color background can lead to perception problems ?
