MAIHDA plot theme

Source: R/theme_maihda.R
theme_maihda.Rd

A ggplot2 theme that applies the MAIHDA brand identity to plot chrome only – navy titles and axis labels and soft slate gridlines. It encodes no data: the colourblind-safe data palettes used by the package's plotting functions are left untouched.

Usage

theme_maihda(base_size = 11, base_family = NULL)

Arguments

base_size

Base font size in points. Default `11`.

base_family

Base font family. Defaults to `getOption("maihda.font", "")`, i.e. the graphics device default unless you have opted into a brand font globally. Pass a string to force a family for a single plot.

Value

A ggplot2 theme object that can be added to a plot with `+`.

Details

Built on [ggplot2::theme_minimal()], so it composes with additional `+ theme()` calls in the usual way (later settings win).

Fonts

By default the theme uses the graphics device's default font, which is safe on every device (including the PostScript/PDF devices used by `R CMD check` and many rendering back-ends). To render figures in the brand font (Montserrat) – matching the hex logo – set `options(maihda.font = "Montserrat")` or pass `base_family = "Montserrat"`, and use a graphics device that can resolve that family (e.g. ragg or showtext). Forcing a font that the active device cannot find produces "invalid font type" errors, which is why it is opt-in rather than automatic.

Examples

library(ggplot2)
ggplot(mtcars, aes(mpg, wt)) +
  geom_point(colour = "#0072B2") +
  labs(title = "MAIHDA brand theme", x = "MPG", y = "Weight") +
  theme_maihda()
