Annotate Rotated Text Label to ggplot2 Graph in R (Example Code)
This page demonstrates how to add a rotated text label to a ggplot2 graphic in R programming.
Preparing the Example
data(iris) # Example data head(iris) # 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 |
install.packages("ggplot2") # Install & load ggplot2 library("ggplot2") |
Example: Adding a Rotated Text Element to a ggplot2 Plot
ggplot(iris, # Add rotated text element aes(x = Sepal.Width, y = Petal.Width)) + geom_line() + annotate("text", x = 3, y = 1.5, label = "This is the Iris Data Set", col = "red", size = 10, angle = 45) |
