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()
Continue to the next pages, to see some simple theme variations…
Default Gray
last_plot() + theme_gray()
Black and White
last_plot() + theme_bw()
Red-Green-Blue and White
last_plot() + theme_tern_rgbw()
Red-Green-Blue and Gray
last_plot() + theme_rgbg()
Without Grid (Minor Only Removed)
last_plot() + theme_bw() + theme_nogrid_minor()
Without Grid (Minor AND Major Removed)
last_plot() + theme_bw() + theme_nogrid()
Without Grid and Without Arrows
last_plot() + theme_bw() + theme_nogrid() + theme_noarrows()

Hej Nick,
I have upgraded to ggtern 2.1.0, but none of the theme functions can be found (R version 3.2.1, Ubuntu 14.04):

Sorry most of these syntaxes are left over (now defunct) from the first version of ggtern, and I havn’t updated the webpage. Ill update this page soon.
Love it! I ran the code shown in the faceting example:
http://www.ggtern.com/faceting/
but the filled contours are missing from my plot. Any ideas?

Hi,
theme_bw() kills the arrows.
MWE
ggtern(data = data.frame(x = 1, y = 1, z = 1), aes(x, y, z)) + geom_point() + theme_showarrows()
# this HAS arrows
last_plot() + theme_bw()
# This does not
