Points, Lines and Arrows in Statistical Graphs

Abstract

Widely used statistical graphs (such as line graphs and bar graphs) are usually accompanied by graphical entities other than the graph proper. Those graphical cues, such as point marks and arrows serve for communicative purposes by bringing certain aspects to the foreground over the others. The present study discusses the results of an experimental investigation, in which the participants produced sketches of graphical cues on different types of graphs, given sentential expressions of states and processes. The outcomes of the study have the potential for serving as guidelines for the development of software tools that produce graphical cues.
