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
`MASS::eqscplot()`

, but it works for all types of graphics.

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

## 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` . |

clip |
Should drawing be clipped to the extent of the plot panel? A
setting of `"on"` (the default) means yes, and a setting of `"off"`
means no. In most cases, the default of `"on"` should not be changed,
as setting `clip = "off"` can cause unexpected results. It allows
drawing of data points anywhere on the plot, including in the plot margins. If
limits are set via `xlim` and `ylim` and some data points fall outside those
limits, then those data points may show up in places such as the axes, the
legend, the plot title, or the plot margins. |

## Examples

p + coord_fixed(ratio = 5)

p + coord_fixed(ratio = 1/5)

p + coord_fixed(xlim = c(15, 30))

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