continuous_scale: 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

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 o

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)?

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()

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.

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.
