\usage{
gradient_color(palette)
gradient_fill(palette)
}
\arguments{
\item{palette}{the color palette to be used for coloring or filling by
groups. Allowed values include "grey" for grey color palettes; brewer
palettes e.g. "RdBu", "Blues", ...; or custom color palette e.g. c("blue",
"red"); and scientific journal palettes from ggsci R package, e.g.: "npg",
"aaas", "lancet", "jco", "ucscgb", "uchicago", "simpsons" and
"rickandmorty". Can be also a numeric vector; in this
case a basic color palette is created using the function
\link[grDevices]{palette}.}
}
\description{
Change gradient color.
\itemize{
\item \code{gradient_color()}: Change gradient color.
\item \code{gradient_fill()}: Change gradient fill.
}
}
\examples{
df <- mtcars
p <- ggscatter(df, x = "wt", y = "mpg",
color = "mpg")
# Change gradient color
# Use one custom color
p + gradient_color("red")
# Two colors
p + gradient_color(c("blue", "red"))
# Three colors
p + gradient_color(c("blue", "white", "red"))
# Use RColorBrewer palette
p + gradient_color("RdYlBu")
# Use ggsci color palette
p + gradient_color("npg")
