Complete themes

These are complete themes which control all non-data display. Use theme() if you just need to tweak the display of an existing theme.

Details

theme_gray()

The signature ggplot2 theme with a grey background and white gridlines, designed to put the data forward yet make comparisons easy.

theme_bw()

The classic dark-on-light ggplot2 theme. May work better for presentations displayed with a projector.

theme_linedraw()

A theme with only black lines of various widths on white backgrounds, reminiscent of a line drawing. Serves a purpose similar to theme_bw(). Note that this theme has some very thin lines (<< 1 pt) which some journals may refuse.

theme_light()

A theme similar to theme_linedraw() but with light grey lines and axes, to direct more attention towards the data.

theme_dark()

The dark cousin of theme_light(), with similar line sizes but a dark background. Useful to make thin coloured lines pop out.

theme_minimal()

A minimalistic theme with no background annotations.

theme_classic()

A classic-looking theme, with x and y axis lines and no gridlines.

theme_void()

A completely empty theme.

theme_test()

A theme for visual unit tests. It should ideally never change except for new features.

Examples

mtcars2 <- within(mtcars, {
  vs <- factor(vs, labels = c("V-shaped", "Straight"))
  am <- factor(am, labels = c("Automatic", "Manual"))
  cyl  <- factor(cyl)
  gear <- factor(gear)
})

p1 <- ggplot(mtcars2) +
  geom_point(aes(x = wt, y = mpg, colour = gear)) +
  labs(
    title = "Fuel economy declines as weight increases",
    subtitle = "(1973-74)",
    caption = "Data from the 1974 Motor Trend US magazine.",
    tag = "Figure 1",
    x = "Weight (1000 lbs)",
    y = "Fuel economy (mpg)",
    colour = "Gears"
  )

p1 + theme_gray() # the default
p1 + theme_bw()
p1 + theme_linedraw()
p1 + theme_light()
p1 + theme_dark()
p1 + theme_minimal()
p1 + theme_classic()
