...
)
Arguments
- name
The name of the scale. Used as the axis or legend title. If
waiver()
, the default, the name of the scale is taken from the first mapping used for that aesthetic. IfNULL
, the legend title will be omitted.- breaks
One of:
NULL
for no breakswaiver()
for the default breaks computed by the transformation objectA numeric vector of positions
A function that takes the limits as input and returns breaks as output (e.g., a function returned by
scales::extended_breaks()
). Also accepts rlang lambda function notation.
- minor_breaks
One of:
NULL
for no minor breakswaiver()
for the default breaks (one minor break between each major break)A numeric vector of positions
A function that given the limits returns a vector of minor breaks. Also accepts rlang lambda function notation.
- n.breaks
An integer guiding the number of major breaks. The algorithm may choose a slightly different number to ensure nice break labels. Will only have an effect if
breaks = waiver()
. UseNULL
to use the default number of breaks given by the transformation.- labels
One of:
NULL
for no labelswaiver()
for the default labels computed by the transformation objectA character vector giving labels (must be same length as
breaks
)An expression vector (must be the same length as breaks). See ?plotmath for details.
A function that takes the breaks as input and returns labels as output. Also accepts rlang lambda function notation.
- limits
One of:
NULL
to use the default scale rangeA numeric vector of length two providing limits of the scale. Use
NA
to refer to the existing minimum or maximumA function that accepts the existing (automatic) limits and returns new limits. Also accepts rlang lambda function notation. Note that setting limits on positional scales will remove data outside of the limits. If the purpose is to zoom, use the limit argument in the coordinate system (see
coord_cartesian()
).
- expand
For position scales, a vector of range expansion constants used to add some padding around the data to ensure that they are placed some distance away from the axes. Use the convenience function
expansion()
to generate the values for theexpand
argument. The defaults are to expand the scale by 5% on each side for continuous variables, and by 0.6 units on each side for discrete variables.- na.value
Missing values will be replaced with this value.
- trans
For continuous scales, the name of a transformation object or the object itself. Built-in transformations include "asn", "atanh", "boxcox", "date", "exp", "hms", "identity", "log", "log10", "log1p", "log2", "logit", "modulus", "probability", "probit", "pseudo_log", "reciprocal", "reverse", "sqrt" and "time".
A transformation object bundles together a transform, its inverse, and methods for generating breaks and labels. Transformation objects are defined in the scales package, and are called
<name>_trans
(e.g.,scales::boxcox_trans()
). You can create your own transformation withscales::trans_new()
.- guide
A function used to create a guide or its name. See
guides()
for more information.- position
For position scales, The position of the axis.
left
orright
for y axes,top
orbottom
for x axes.- sec.axis
sec_axis()
is used to specify a secondary axis.- coef
Multiplier for the second axis to be expanded
- sec.name
axis name of second axis
- ...
