\title{Expand the plot limits, using data}
\usage{
expand_limits(...)
}
\arguments{
\item{...}{named list of aesthetics specifying the value (or values) that
should be included in each scale.}
}
\description{
Sometimes you may want to ensure limits include a single value, for all
panels or all plots.  This function is a thin wrapper around
\code{\link[=geom_blank]{geom_blank()}} that makes it easy to add such values.

\examples{
p <- ggplot(mtcars, aes(mpg, wt)) + geom_point()
p + expand_limits(x = 0)
p + expand_limits(y = c(1, 9))
p + expand_limits(x = 0, y = 0)

ggplot(mtcars, aes(mpg, wt)) +
  geom_point(aes(colour = cyl)) +
  expand_limits(colour = seq(2, 10, by = 2))
ggplot(mtcars, aes(mpg, wt)) +
  geom_point(aes(colour = factor(cyl))) +
  expand_limits(colour = factor(seq(2, 10, by = 2)))
