Modify ggplot2 Facet Label Background & Text Colors in R (Example Code)
This tutorial demonstrates how to change the facet label background and text colors of a ggplot2 plot in the R programming language.
Setting up 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 ggplot2 package library("ggplot2") # Load ggplot2 |
my_plot <- ggplot(iris, # Draw facet_wrap plot aes(x = Sepal.Length, y = Petal.Length)) + geom_point() + facet_wrap(~ Species) my_plot |
Example: Change Background & Text Colors of ggplot2 facet_wrap Plot
my_plot + theme(strip.background = element_rect(fill = "pink")) + theme(strip.text = element_text(colour = "blue")) |
