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.
the Unstack (checkbox) functionality is just divine !
i hope this becomes part of the Analyze > Distribution and / or Graph Builder platforms.
also, can i use the Unstack script and add it in Graph Builder when i want to achieve the unstacked layout?
