Continuous scale constructor.

Description

Continuous scale constructor.

Usage

continuous_scale(
  aesthetics,
  scale_name,
  palette,
  name = waiver(),
  breaks = waiver(),
  minor_breaks = waiver(),
  labels = waiver(),
  limits = NULL,
  rescaler = rescale,
  oob = censor,
  expand = waiver(),
  na.value = NA_real_,
  trans = "identity",
  guide = "legend"
)

Arguments

`aesthetics`	the names of the aesthetics that this scale works with
`scale_name`	the name of the scale
`palette`	a palette function that when called with a single integer argument (the number of levels in the scale) returns the values that they should take
`name`	The name of the scale. Used as axis or legend title. If `NULL`, the default, the name of the scale is taken from the first mapping used for that aesthetic.
`breaks`	One of: `NULL` for no breaks `waiver()` for the default breaks computed by the transformation object A numeric vector of positions A function that takes the limits as input and returns breaks as output
`minor_breaks`	One of: `NULL` for no minor breaks `waiver()` 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.
`labels`	One of: `NULL` for no labels `waiver()` for the default labels computed by the transformation object A character vector giving labels (must be same length as `breaks`) A function that takes the breaks as input and returns labels as output
`limits`	A numeric vector of length two providing limits of the scale. Use `NA` to refer to the existing minimum or maximum.
`rescaler`	Used by diverging and n colour gradients (i.e. `scale_colour_gradient2`, `scale_colour_gradientn`). A function used to scale the input values to the range [0, 1].
`oob`	Function that handles limits outside of the scale limits (out of bounds). The default replaces out of bounds values with NA.
`expand`	A numeric vector of length two giving multiplicative and additive expansion constants. These constants ensure that the data is placed some distance away from the axes. The defaults are `c(0.05, 0)` for continuous variables, and `c(0, 0.6)` for discrete variables.
`na.value`	Missing values will be replaced with this value.
`trans`	Either the name of a transformation object, or the object itself. Built-in transformations include "asn", "atanh", "boxcox", "exp", "identity", "log", "log10", "log1p", "log2", "logit", "probability", "probit", "reciprocal", "reverse" and "sqrt". A transformation object bundles together a transform, it's inverse, and methods for generating breaks and labels. Transformation objects are defined in the scales package, and are called `name_trans`, e.g. `boxcox_trans`. You can create your own transformation with `trans_new`.
`guide`	Name of guide object, or object itself.
