Customizing Fonts and Colors with ggplot2

Customizing fonts and colors

After building a data visualization, the next step can be customization. We can customize the font and colors of various plot elements in ggplot2 to effectively communicate our data and enhance the aesthetic appeal of the plot using the theme() function.

Using the element_text() function inside the theme() function, we can customize the font, font family, and color of plot elements such as the title, subtitle, caption, and tag.

Let’s first create a simple pie chart using the housing dataset from the MASS package. We’ll also add a title, subtitle, caption, and tag to the plot and save it in an object named chart. Then, we’ll customize this plot.
