This folder contains theme files for common plotting libraries, to quickly style charts to reflect Trase branding.

ggplot2

With your working directory set to the TRASE_ANALYSIS repository on your local machine, run source("themes/theme_trase.R") to load a few objects into your current R environment:

  • theme_trase, a ggplot theme
  • trase_palette_categorical, a 10-colour Trase-branded color palette for categorical variables
  • trase_palette_categorical2, a 5-colour Trase-branded color palette for categorical variables
  • trase_palette_linear, an 8-colour Trase-branded linear palette
  • trase_palette_linear2, a 9-colour Trase-branded linear palette
  • trase_palette_grey, a grey Trase-branded linear palette
  • trase_palette_green, a green Trase-branded linear palette

There are also specific colours for different plot elements - trase_map_border, for jurisdiction borders in maps - trase_country_background, the background colour of focus jurisdictions

Then, add theme_trase() and the color palettes to your plot call as your would for any other ggplot theme. 

library(ggplot2)
library(extrafont) # needed to load Trase fonts Decima Mono Pro and Merriweather. See below for installation.

# theme applied without Trase color palette
ggplot(iris, aes(x = Sepal.Length, y = Sepal.Width, color = Species)) + 
  geom_point() + 
  theme_trase()

# theme and color palette applied
ggplot(iris, aes(x = Sepal.Length, y = Sepal.Width, color = Species)) + 
  geom_point() + 
  theme_trase() + 
  scale_color_manual(values = trase_palette_linear)

Example plots are shown in the THEME_EXAMPLES folder.

Note on fonts: this theme works best with Trase fonts installed on your machine, which can be downloaded from the Trase dropbox at https://www.dropbox.com/work/Trase/3.%20workstreams/ws4.%20frontend/8.%20design%20assets/Fonts, as well as for fonts to be registered in R (extrafont::loadfonts() is helpful for this).
