# Fix Aspect Ratio in ggplot2 Plot in R (2 Examples)

In this R tutorial you’ll learn how to use the coord_fixed function to set a fixed aspect ratio.

The table of content is structured as follows:

Let’s jump right to the examples:

## Exemplifying Data, Add-On Packages & Default Plot

As a first step, we’ll need to create some example data:

```set.seed(347865) # Example data data <- data.frame(x = rnorm(100, 0, 5), y = rnorm(100)) head(data) # Print head of example data # x y # 1 5.320164 -0.62260359 # 2 -10.665791 -0.06837196 # 3 -3.872701 -0.19777942 # 4 -4.781276 -0.83737958 # 5 -4.704341 -0.24583468 # 6 2.868131 -0.44292606```

The previous output of the RStudio console shows that our exemplifying data has two numeric columns with the names x and y.

If we want to plot our data with the ggplot2 add-on package, we also need to install and load ggplot2:

```install.packages("ggplot2") # Install & load ggplot2 library("ggplot2")```

Next, we can plot our data:

```ggp <- ggplot(data, aes(x, y)) + # Basic ggplot2 plot geom_point() ggp # Print basic ggplot2 plot``` As shown in Figure 1, we drew a basic ggplot2 scatterplot with the previous R syntax.

## Example 1: Fixed Aspect Ratio Using coord_fixed Function

In this Example, I’ll illustrate how to set a fixed aspect ratio in a ggplot2 plot in R. Have a look at the following R code:

`ggp + coord_fixed() # Apply coord_fixed` The output of the previous R programming syntax is visualized in Figure 2: You can see a ggplot2 scatterplot with fixed proportions of the x- and y-axes. This fixed aspect ratio is set to 1 in this example.

## Example 2: Fixed Aspect Ratio Using coord_fixed Function & ratio Argument

Example 2 shows how to set aspect ratios with a different ratio than 1. In the example, we’ll use an aspect ratio of 5:

`ggp + coord_fixed(ratio = 5) # Apply coord_fixed & ratio` The output of the previous R syntax is illustrated in Figure 3: As you can see the aspect ratio is still fixed, but with a different ratio of the two axes.

The YouTube video will be added soon.

To summarize: In this post, I illustrated how to fix aspect ratios of ggplot2 graphics and change the proportions from square to rectangle in R programming. Don’t hesitate to let me know in the comments below, in case you have any further questions.
