But, unlike a bar chart, which uses length to relay position, Cleveland dot plots use position. William S. Cleveland created the notion of a continuous variable in his book Elements of Graphing Data.

The interaction of trial type × graph type, F(1.67,63.63) = 16.48, p < 0.001, η p 2 = 0.30, indicated that trial type affected the processing times on bar graphs and dot plots differently: Bar graphs ...

A dot plot is judged by its position along an axis; in this case, the horizontal or x axis. A bar chart is judged by the length of the bar. I don’t like using lengths with logarithmic scales.

Different graph types might differ in group comparison due to differences in underlying graph schemas. Thus, this study examined whether graph schemas are based on perceptual features (i.e., each ...
