\title{coord\_fixed}
\description{Cartesian coordinates with fixed relationship between x and y scales.}
\details{
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, 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 ?eqscplot in MASS, but it works for all types of graphics
This page describes coord\_fixed, see \code{\link{layer}} and \code{\link{qplot}} for how to create a complete plot from individual components.
