Available Themes

One of the great features of ggplot2, is the way in which the theme architecture has been implemented. It is very easy to ‘customize’ a plot the way that you like, and, historically, several convenience functions were provided to make it even easier, such as theme_bw() or theme_gray(). In this spirit, ggtern has also implemented some theme-based convenience functions, and the purpose of this post is to illustrate the differences.

Firstly, lets create a default plot:

library(ggtern)
plot <- ggtern(data = data.frame(x = 1, y = 1, z = 1),
               aes(x, y, z)) +
        geom_point()
