R: Continuous scale constructor.

continuous_scale {ggplot2}

R Documentation

Continuous scale constructor.

Description

Continuous scale constructor.

Usage

continuous_scale(aesthetics, scale_name, palette, name = NULL,
  breaks = waiver(), minor_breaks = waiver(), labels = waiver(),
  legend = NULL, 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 the axis label or the legend title
`breaks`	control the breaks in the guide. There are four possible types of input: `NULL`: don't display any breaks a character vector giving the breaks as they should appear on the axis or in the legend. `waiver()` to use the default break computation. a function, that when called with a single argument, a character vector giving the limits of the scale, returns a character vector specifying which breaks to display. This parameter does not affect in any way how the data is scaled - it only affects the appearance of the legend.
`minor_breaks`	Used with date or datetime scales. Either `NULL` for no minor breaks, `waiver()` for the default breaks (one minor break between each major break), a numeric vector of positions, or a function that given the limits returns a vector of minor breaks.
`labels`	`NULL` for no labels, `waiver()` for default labels (labels the same as breaks), a character vector the same length as breaks, or a named character vector whose names are used to match replacement the labels for matching breaks.
`legend`	deprecated. Use `guide` instead.
`limits`	A numeric vector of length two describing the scale limits.
`rescaler`	Used by diverging and n colour gradients (i.e. `scale_colour_gradient2`, `scale_colour_gradientn`).
`oob`	What to do with values outside scale limits (out of bounds)?
`expand`	a numeric vector of length two, giving a multiplicative and additive constant used to expand the range of the scales so that there is a small gap between the data and the axes.
`na.value`	how should missing values be displayed?
`guide`	the name of, or actual function, used to create the guide.
