Dot-dash-plot marginal distributions — geom

Add a short tick for each observation along the plot's margins. Tufte's dot-dash plot uses these ticks to show the marginal distributions beside a scatterplot.

Usage

geom_dotdash(
  mapping = NULL,
  data = NULL,
  stat = "identity",
  position = "identity",
  ...,
  sides = "bl",
  tick_length = grid::unit(0.02, "npc"),
  na.rm = FALSE,
  show.legend = NA,
  inherit.aes = TRUE
)

Arguments

mapping, data, stat, position, na.rm, show.legend, inherit.aes, ...: Standard ggplot2 layer arguments. See layer().
sides: Which margins to draw on, as a string containing any of "b", "l", "t", "r". Defaults to "bl".
tick_length: Tick length, as a unit. Defaults to 2 percent of the panel.

Value

A ggplot2 layer.

Details

The default ticks are short and thin. Use theme_tufte(ticks = FALSE) if you'd like them to replace the ordinary axis ticks.

Examples

library(ggplot2)
ggplot(mtcars, aes(wt, mpg)) +
  geom_point() +
  geom_dotdash() +
  theme_tufte(ticks = FALSE)
