# coord_fixed

From ggplot2 v0.9.3.1
by Hadley Wickham

##### Cartesian coordinates with fixed relationship between x and y scales.

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.

##### Usage

```
coord_fixed(ratio = 1, xlim = NULL, ylim = NULL,
wise = NULL)
```

##### Arguments

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

- xlim
- limits for the x axis
- ylim
- limits for the y axis
- wise
- deprecated in 0.9.1

##### 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
```
