Change Labels of ggplot2 Facet Plot to Italics & Bold in R (2 Examples)
In this article, I’ll show how to switch the labels of a ggplot2 facet graphic to bold or italics in the R programming language.
Setting up the Examples
data(iris) # Importing 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 ggplot2 package library("ggplot2") # Load ggplot2 |
my_plot <- ggplot(iris, # Draw ggplot2 facet plot aes(x = Petal.Length, y = Petal.Width)) + geom_point() + facet_wrap(. ~ Species) my_plot |
Example 1: Changing Labels of ggplot2 Facet Plot to Italics
my_plot + # Convert labels to italics theme(strip.text = element_text(face = "italic")) |
Example 2: Changing Labels of ggplot2 Facet Plot to Bold
my_plot + # Convert labels to bold theme(strip.text = element_text(face = "bold")) |
