Discrete and Continuous Fill Scale Using generate_colors

Drop-in replacement for viridis::scale_fill_viridis() that works with any palette supported by generate_colors().

Usage

scale_fill_generate(palette = "viridis", discrete = TRUE, ...)

scale_color_generate(palette = "viridis", discrete = TRUE, ...)

Arguments

palette

Passed to generate_colors(). Either a palette name string or a function.

discrete

logical. If TRUE (default), a discrete scale is returned. If FALSE, a continuous scale is returned.

...

Additional arguments passed to ggplot2::scale_fill_manual() (discrete) or ggplot2::scale_fill_gradientn() (continuous).

# Discrete
ggplot(mtcars, aes(x = wt, y = mpg, fill = factor(cyl))) +
  geom_col() +
  scale_fill_generate(palette = "Set1")


# Continuous
ggplot(mtcars, aes(x = wt, y = mpg, fill = mpg)) +
  geom_point(shape = 21, size = 3) +
  scale_fill_generate(palette = "viridis", discrete = FALSE)


ggplot(mtcars, aes(x = wt, y = mpg, color = factor(cyl))) +
  geom_point() +
