2D Box Plots - Multiple (Format)

Unlike regular box plots in which the range of values of one variable is represented, the multiple box plot represents ranges of values of multiple variables.

When a grouping variable is selected, a different fill pattern and color is used for each of the multiple variables. Point marker patterns are the same for all raw data, outliers, and extremes across variables, since the points of different plots are perfectly separated. Note that fill patterns, colors, and point markers are all referenced in the graph legend.

This type of box plot is used to compare ranges of values between several variables (or several functions) by overlaying them in a single graph that uses one common set of scales (e.g., comparisons between several simultaneous experimental processes, social phenomena, stock or commodity quotes, shapes of operating characteristics curves, etc.).
