Continuous scChromatic color scale — scale_color_sc

A non-NULL midpoint uses scales::rescale_mid() so the data value at the midpoint maps to the center of the gradient.

Usage

scale_color_sc_c(
  palette = "viridis",
  alpha = 1,
  reverse = FALSE,
  midpoint = NULL,
  limits = NULL,
  oob = scales::squish,
  na.value = "grey85",
  ...
)

scale_colour_sc_c(
  palette = "viridis",
  alpha = 1,
  reverse = FALSE,
  midpoint = NULL,
  limits = NULL,
  oob = scales::squish,
  na.value = "grey85",
  ...
)

scale_fill_sc_c(
  palette = "viridis",
  alpha = 1,
  reverse = FALSE,
  midpoint = NULL,
  limits = NULL,
  oob = scales::squish,
  na.value = "grey85",
  ...
)

Arguments

palette: Sequential, diverging, or cyclic palette ID.
alpha: Opacity in (0, 1].
reverse: Reverse the color sequence.
midpoint: Optional data midpoint.
limits: Scale limits.
oob: Out-of-bounds handler.
na.value: Missing-value color.
...: Passed to ggplot2::scale_color_gradientn() or its fill variant.

Value

A ggplot2 continuous scale.

Details

Use the color or colour variant for numeric variables mapped to color, and the fill variant for numeric variables mapped to fill. Continuous scales accept sequential, diverging, or cyclic palettes, not qualitative palettes. For categories, use the _sc_d() family or a persistent _sc_map() scale.

Examples

ggplot2::ggplot(mtcars, ggplot2::aes(wt, mpg, color = disp)) +
  ggplot2::geom_point() + scale_color_sc_c("viridis")
