Dot Plot

A dot plot, also called a dot chart, is a type of simple histogram-like chart used in statistics for relatively small data sets where values fall into a number of discrete bins. To draw a dot plot, count the number of data points falling in each bin and draw a stack of dots that number high for each bin. The illustration above shows such a plot for a random sample of 100 integers chosen between 1 and 25 inclusively.

Simple code for drawing a dot plot in the Wolfram Language with some appropriate labeling of bin heights can be given as

DotPlot[data_] := Module[{m = Tally[Sort[data]]},
  ListPlot[Flatten[Table[{#1, n}, {n, #2}]& @@@ m, 1],
   Ticks -> {Automatic, Range[0, Max[m[[All, 2]]]]}]
]
