Gradient color palettes using the diverging and sequential continuous color palettes in Tableau. See tableau_color_pal() for discrete color palettes.

Usage

tableau_gradient_pal(palette = "Blue", type = "ordered-sequential")

tableau_seq_gradient_pal(palette = "Blue", ...)

tableau_div_gradient_pal(palette = "Orange-Blue Diverging", ...)

Arguments

  • "ordered-sequential": "Blue-Green Sequential", "Blue Light", "Orange Light", "Blue", "Orange", "Green", "Red", "Purple", "Brown", "Gray", "Gray Warm", "Blue-Teal", "Orange-Gold", "Green-Gold", "Red-Gold", "Classic Green", "Classic Gray", "Classic Blue", "Classic Red", "Classic Orange", "Classic Area Red", "Classic Area Green", "Classic Area Brown".

  • "ordered-diverging": "Orange-Blue Diverging", "Red-Green Diverging", "Green-Blue Diverging", "Red-Blue Diverging", "Red-Black Diverging", "Gold-Purple Diverging", "Red-Green-Gold Diverging", "Sunset-Sunrise Diverging", "Orange-Blue-White Diverging", "Red-Green-White Diverging", "Green-Blue-White Diverging", "Red-Blue-White Diverging", "Red-Black-White Diverging", "Orange-Blue Light Diverging", "Temperature Diverging", "Classic Red-Green", "Classic Red-Blue", "Classic Red-Black", "Classic Area Red-Green", "Classic Orange-Blue", "Classic Green-Blue", "Classic Red-White-Green", "Classic Red-White-Black", "Classic Orange-White-Blue", "Classic Red-White-Black Light", "Classic Orange-White-Blue Light", "Classic Red-White-Green Light", "Classic Red-Green Light".

  • "ordered-diverging": diverging palettes.

...

Arguments passed to tableau_gradient_pal.

Value

A palette function. It takes a numeric vector x of values between 0 and 1 and returns a character vector of hex colors interpolated along the palette, for use as the palette argument of ggplot2::continuous_scale().

Examples

x <- seq(0, 1, length = 25)
r <- sqrt(outer(x^2, x^2, "+"))
palettes <-
  ggthemes_data[["tableau"]][["color-palettes"]][["ordered-sequential"]]
for (palname in names(palettes)) {
  col <- tableau_seq_gradient_pal(palname)(seq(0, 1, length = 12))
  image(r, col = col)
  title(main = palname)
