A statistical (aka Wilkinson) dot plot is included with JMP 11.
It's under Help > Sample Data > Teaching Demonstrations > Dot Plot.
For JMP 10, this add-in provides the same functionality. The add-in was written by JMP intern Shang Ding.
See Shang's statistical dot plot blog post for details.
See my Two Kinds of Dot Plots post on the term dot plot.
