A sparge plot is a diagram depicting the spread of numerical data of one (or more) univariate distribution(s) using a combination of jittered and translucent points and superimposing subtle (e.g. white) boxplot(s) over the darker central collection of datapoints.[1][2]

a colorful sparge plot with 10 variables as rows of 4 overlapping distributions smeared across the plot as horizontal streaks. Each color corresponds to a different outcome variable.

Sparge plots are similar to sina plots in displaying the points themselves, but sina plots depict kernel density and sparge plots use a boxplot overlay to quantitatively demarcate partitions of distributional spread.

An easy way to create a sparge plot is by using the 'plot.sparge' function in the 'caroline' R-package:

  • The caroline library of the R programming language.[3]
