Annotate axis ticks

Source: R/axis-ticks.R
axis_ticks.Rd

Draws axis ticks at specified break positions, with style defaults taken from the axis.ticks element of the set theme. Requires coord_cartesian(clip = "off").

Usage

axis_ticks(
  ...,
  position = NULL,
  xintercept = NULL,
  yintercept = NULL,
  breaks,
  minor = FALSE,
  colour = NULL,
  linewidth = NULL,
  length = ggplot2::rel(1)
)

Arguments

...

Not used. Forces named arguments.

position

One of "top", "bottom", "left", or "right". Inferred from xintercept or yintercept if not provided.

xintercept

For "left"/"right" axes: float the axis to this x position in data coordinates instead of the panel edge.

yintercept

For "top"/"bottom" axes: float the axis to this y position in data coordinates instead of the panel edge.

breaks

A numeric vector of break positions.

minor

Logical. If TRUE, uses minor tick theme defaults. Defaults to FALSE.

colour

Inherits from axis.ticks in the set theme.

linewidth

Inherits from axis.ticks in the set theme. Supports rel().

length

Total tick length as a grid unit. Supports rel(). Negative values flip the tick direction (inward). Defaults to rel(1) (outward at theme tick length).

Value

A list of ggplot2 annotation layers.
