This document shows examples how to create b/w figures, e.g. if you don’t want colored figures for print-journals.

Barplots in grey-scaled colors

There are two ways to create plots in black and white or greyscale. For bar plots, geom.colors = "gs" creates a plot using a greyscale (based on scales::grey_pal()).

Lineplots in b/w with different linetypes

Similar to barplots, lineplots - mostly from plot_model() - can be plotted in greyscale as well (with colors = "gs"). However, in most cases lines colored in greyscale are difficult to distinguish. In this case, plot_model() supports black & white figures with different linetypes. Use colors = "bw" to create a b/w-plot.

Different linetypes do not apply to all linetyped plots, if these usually only plot a single line - so there’s no need for different linetypes, and you can just set colors = "black" (or colors = "bw").
