The hat plot representation in TinkerPlots is a precursor to the introduction of box plots and can be used to describe general differences in the shapes of distributions.
The analysis outcomes reported at the bottom of the Figures 2 through 5 are based on parametric statistical tests (post hoc univariate analysis of variance with Tukey correction), whereas the box plots are nonparametric per limitation of the graphing software.
A sensible way to introduce box plots is via the stacked dot plot, so that you can see that the smaller the box (or half a box if we are talking about a quartile), the more densely packed it is.
