- long, mid, short
A grid::unit()
object or rel()
object setting
the (relative) length of the long, middle and short ticks. Numeric values
are interpreted as rel()
objects. The rel()
values are used to multiply
values of the axis.ticks.length
theme setting.
- prescale_base
Base of logarithm used to transform data manually. The
default, NULL
, will use the scale transformation to calculate positions.
Only set prescale_base
if the data has already been log-transformed.
When using a log-transform in the position scale or in coord_trans()
,
keep the default NULL
argument.
- negative_small
When the scale limits include 0 or negative numbers,
what should be the smallest absolute value that is marked with a tick?
- short_theme
A theme element for customising the
display of the shortest ticks. Must be a line or blank element, and
it inherits from the axis.minor.ticks
setting for the relevant position.
- expanded
Whether the ticks should cover the range after scale
expansion (TRUE
, default), or be restricted to the scale limits
(FALSE
).
- cap
A character
to cut the axis line back to the last breaks. Can
be "none"
(default) to draw the axis line along the whole panel, or
"upper"
and "lower"
to draw the axis to the upper or lower break, or
"both"
to only draw the line in between the most extreme breaks. TRUE
and FALSE
are shorthand for "both"
and "none"
respectively.
- theme
A theme
object to style the guide individually or
differently from the plot's theme settings. The theme
argument in the
guide overrides, and is combined with, the plot's theme.
- ...
Arguments passed on to guide_axis
check.overlap
silently remove overlapping labels,
(recursively) prioritizing the first, last, and middle labels.
angle
Compared to setting the angle in theme()
/ element_text()
,
this also uses some heuristics to automatically pick the hjust
and vjust
that
you probably want. Can be one of the following:
NULL
to take the angles and hjust
/vjust
directly from the theme.
waiver()
to allow reasonable defaults in special cases.
A number representing the text angle in degrees.
n.dodge
The number of rows (for vertical axes) or columns (for
horizontal axes) that should be used to render the labels. This is
useful for displaying labels that would otherwise overlap.
order
A positive integer
of length 1 that specifies the order of
this guide among multiple guides. This controls in which order guides are
merged if there are multiple guides for the same position. If 0 (default),
the order is determined by a secret algorithm.
position
Where this guide should be drawn: one of top, bottom,
left, or right.
title
A character string or expression indicating a title of guide.
If NULL
, the title is not shown. By default
(waiver()
), the name of the scale object or the name
specified in labs()
is used for the title.
