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()
). Note that for position scales, limits are provided after scale expansion. 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. When the function has two arguments, it will be given the limits and major breaks.
- guide
A function used to create a guide or its name. See
guides()
for more information.- 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.- oob
One of:
Function that handles limits outside of the scale limits (out of bounds). Also accepts rlang lambda function notation.
The default (
scales::censor()
) replaces out of bounds values withNA
.scales::squish()
for squishing out of bounds values into range.scales::squish_infinite()
for squishing infinite values into range.
- na.value
Missing values will be replaced with this value.
- trans
- 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.- accuracy
A number to round to. Use (e.g.)
0.01
to show 2 decimal places of precision. IfNULL
, the default, uses a heuristic that should ensure breaks have the minimum number of digits needed to show the difference between adjacent values.Applied to rescaled data.
- scale
A scaling factor:
x
will be multiplied byscale
before formatting. This is useful if the underlying data is very small or very large.- prefix
Additional text to display before the number. The suffix is applied to absolute value before
style_positive
andstyle_negative
are processed so thatprefix = "$"
will yield (e.g.)-$1
and($1)
.- suffix
Additional text to display after the number.
- big.mark
Character used between every 3 digits to separate thousands.
- decimal.mark
The character to be used to indicate the numeric decimal point.
- trim
Logical, if
FALSE
, values are right-justified to a common width (seebase::format()
).- ...
Other arguments passed on to
scale_(x|y)_continuous()
- currency
currency symbol
