Abstract
Visual elements such as grids, labels, and contour lines act as reference structures or visual metadata that support the primary information being presented. Such structures need to be usefully visible, but not so obtrusive that they clutter the presentation. Our goal is to determine the physical, perceptual and cognitive characteristics of such structures, ideally in a way that enables their automatic computation. This experiment presents our first results towards characterizing the properties of grids. Specifically, we present the result of a set of experiments to determine effective display ranges, described in terms of transparency (alpha), for thin rectangular grids over scatterplot data.
