\title{Area plot.}
\usage{
geom_area(mapping = NULL, data = NULL, stat = "identity",
  position = "stack", na.rm = FALSE, ...)
}
\arguments{
\item{mapping}{The aesthetic mapping, usually constructed with
\code{\link{aes}} or \code{\link{aes_string}}. Only needs to be set
at the layer level if you are overriding the plot defaults.}

\item{data}{A layer specific dataset - only needed if you want to override
the plot defaults.}

\item{stat}{The statistical transformation to use on the data for this
layer.}

\item{position}{The position adjustment to use for overlapping points
on this layer}

\item{na.rm}{If \code{FALSE} (the default), removes missing values with
a warning.  If \code{TRUE} silently removes missing values.}

\item{...}{other arguments passed on to \code{\link{layer}}. This can
include aesthetics whose values you want to set, not map. See
\code{\link{layer}} for more details.}
}
\description{
An area plot is the continuous analog of a stacked bar chart (see
\code{\link{geom_bar}}), and can be used to show how composition of the
whole varies over the range of x.  Choosing the order in which different
components is stacked is very important, as it becomes increasing hard to
see the individual pattern as you move up the stack.
}
\details{
An area plot is a special case of \code{\link{geom_ribbon}}, where the
minimum of the range is fixed to 0, and the position adjustment defaults
to position_stacked.
