## Usage

coord_fixed(ratio = 1, xlim = NULL, ylim = NULL, expand = TRUE)

## Arguments

- ratio
- aspect ratio, expressed as
`y / x`

- xlim
- Limits for the x and y axes.
- ylim
- Limits for the x and y axes.
- expand
- If
`TRUE`

, the default, adds a small expansion factor to
the limits to ensure that data and axes don't overlap. If `FALSE`

,
limits are taken exactly from the data or `xlim`

/`ylim`

.

## 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, `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`

, 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
p <- ggplot(mtcars, aes(mpg, wt)) + geom_point()
p + coord_fixed(ratio = 1)

p + coord_fixed(ratio = 5)

p + coord_fixed(ratio = 1/5)

# Resize the plot to see that the specified aspect ratio is maintained
