Differences in comprehensibility between three-variable bar and line graphs
<20>This paper challenges the widely held view that line graphs are the optimal format for presenting data from factorial research designs. The study demonstrated significant deficits in non-expert user's ability to comprehend data in line graphs compared to equivalent bar graphs. The importance of this research lies in its re-evaluation of line graphs in this context by showing that pattern recognition processes, often considered to be beneficial for guiding interpretation, can hinder non-expert users' ability to identify the range of relationships depicted. It also demonstrates that interface designs should be evaluated for a range of users, not exclusively for experts.
