scale_fill_albums {taylor}

Taylor Swift colour scale for album comparisons

Description

A convenience wrapper for comparing albums with color. In contrast to scale_fill_taylor_d() and scale_colour_taylor_d(), scale_fill_albums() and scale_colour_albums() use a single palette, with one color per album. Specifically, the album_compare palette is used to apply a color associated with each album.

Usage

scale_fill_albums(
  ...,
  aesthetics = "fill",
  breaks = waiver(),
  limits = force,
  na.value = NA
)

scale_colour_albums(
  ...,
  aesthetics = "colour",
  breaks = waiver(),
  limits = force,
  na.value = NA
)

scale_color_albums(
  ...,
  aesthetics = "colour",
  breaks = waiver(),
  limits = force,
  na.value = NA
)

Arguments

...

Other arguments to be passed to ggplot2::discrete_scale()

aesthetics

The names of the aesthetics that this scale works with.

breaks

One of:

• NULL for no breaks

• waiver() for the default breaks (the scale limits)

• A character vector of breaks

• A function that takes the limits as input and returns breaks as output. Also accepts rlang lambda function notation.

limits

One of:

• NULL to use the default scale values

• A character vector that defines possible values of the scale and their order

• A function that accepts the existing (automatic) values and returns new ones. Also accepts rlang lambda function notation.

na.value

If na.translate = TRUE, what aesthetic value should the missing values be displayed as? Does not apply to position scales where NA is always placed at the far right.

Value

A color scale for use in plots created with ggplot2::ggplot().

Examples

library(ggplot2)
studio <- subset(taylor_albums, !is.na(metacritic_score))

# create a plot that we want to color or fill by album
ggplot(studio, aes(x = metacritic_score, y = album_name)) +
  geom_col(aes(fill = album_name))

# apply a color inspired by each album cover
ggplot(studio, aes(x = metacritic_score, y = album_name)) +
  geom_col(aes(fill = album_name)) +
  scale_fill_albums()

# even when the axis or levels are rearranged, the correct color is applied
studio$album_name <- factor(studio$album_name, levels = album_levels)
ggplot(studio, aes(x = metacritic_score, y = album_name)) +
  geom_col(aes(fill = album_name)) +
  scale_fill_albums()
