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

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()

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

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.
