\alias{coord_equal}
\alias{coord_fixed}
\title{Cartesian coordinates with fixed relationship between x and y scales.}
\usage{
coord_fixed(ratio = 1, xlim = NULL, ylim = NULL, wise = NULL)
}
\arguments{
\item{ratio}{aspect ratio, expressed as \code{y / x}}
\item{xlim}{limits for the x axis}
\item{ylim}{limits for the y axis}
\item{wise}{deprecated in 0.9.1}
}
\description{
A fixed scale coordinate system forces a specified ratio between the
physical representation of data units on the axes. The ratio represents the
number of units on the y-axis equivalent to one unit on the x-axis. The
default, \code{ratio = 1}, ensures that one unit on the x-axis is the same
length as one unit on the y-axis. Ratios higher than one make units on the
y axis longer than units on the x-axis, and vice versa. This is similar to
\code{\link[MASS]{eqscplot}}, but it works for all types of graphics.
}
\examples{
# ensures that the ranges of axes are equal to the specified ratio by
# adjusting the plot aspect ratio
qplot(mpg, wt, data = mtcars) + coord_fixed(ratio = 1)
qplot(mpg, wt, data = mtcars) + coord_fixed(ratio = 5)
qplot(mpg, wt, data = mtcars) + coord_fixed(ratio = 1/5)
# Resize the plot to see that the specified aspect ratio is maintained
