# coord_fixed: Cartesian coordinates with fixed "aspect ratio" In ggplot2: Create Elegant Data Visualisations Using the Grammar of Graphics

## 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.

## Usage

 `1` ```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`.

## Examples

 ```1 2 3 4 5 6 7 8 9``` ```# 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 ```
