# Reverse Y-Axis Scale of Base R & ggplot2 Graph (2 Examples)

In this tutorial you’ll learn how to exchange the axis limits of a graphic in the R programming language.

## Setting up the Examples

```data(iris) # Loading example data head(iris) # Displaying data in RStudio console # Sepal.Length Sepal.Width Petal.Length Petal.Width Species # 1 5.1 3.5 1.4 0.2 setosa # 2 4.9 3.0 1.4 0.2 setosa # 3 4.7 3.2 1.3 0.2 setosa # 4 4.6 3.1 1.5 0.2 setosa # 5 5.0 3.6 1.4 0.2 setosa # 6 5.4 3.9 1.7 0.4 setosa```

## Example 1: Reverse Y-Axis Scale in Graphic Using Base R

```plot(x = iris\$Sepal.Length, # Regular axis y = iris\$Sepal.Width)```

```plot(x = iris\$Sepal.Length, # Reversed axis y = iris\$Sepal.Width, ylim = rev(range(iris\$Sepal.Width)))```

## Example 2: Reverse Y-Axis Scale in Graphic Using the ggplot2 Package

```install.packages("ggplot2") # Install ggplot2 package library("ggplot2") # Load ggplot2```
```my_plot <- ggplot(iris, # Regular axis aes(x = Sepal.Length, y = Sepal.Width)) + geom_point() my_plot```

```my_plot + # Reversed axis scale_y_reverse()```
