ggsketch (version 2.0.0)

scale_medium_discrete: Discrete scale for the drawing medium aesthetic

Description

Maps a discrete variable to drawing media (see sketch_media()) when it is mapped with aes(medium = ) on a path-like sketch geom (geom_sketch_line(), geom_sketch_path(), geom_sketch_segment(), geom_sketch_step()). Because of its name, ggplot2 picks it up automatically; you only need to call it directly to choose which media to use or to set legend options.

Usage

scale_medium_discrete(..., media = NULL)

Value

A ggplot2 scale object.

Arguments

...

Passed to ggplot2::discrete_scale() (e.g. name, labels, guide).

media

Character vector of media to cycle through, each one of sketch_media(). Defaults to every medium except "pen" (so mapped levels look distinct); recycled with a warning if there are more levels than media.

Details

Each group is drawn in a single medium, so map medium to the same variable you group by (often colour or group).

  g = rep(c("a", "b", "c"), each = 10)
)
ggplot(df, aes(x, y, group = g, medium = g, colour = g)) +
