Scales

Description

Scales map data values to visual properties. Every scale is set with one function, ⁠set_scale(<aesthetic>, <type>, ...)⁠, where the aesthetic is the channel (such as "x" or "color") and the type is how values are mapped (such as "log" or "time"). scale_color(), scale_log() and scale_time() are shortcuts for common cases.

Usage

scale_color(spec, palette = "Tableau10", ...)

scale_log(spec, aesthetic = "y", base = 10, ...)

scale_time(spec, aesthetic = "x", ...)

Arguments

spec	A glyph_spec
palette	A named palette: "viridis", "Set2", "Tableau10", "Blues", etc.
...	Additional arguments passed to set_scale()
aesthetic	Which channel: "x", "y", "color", "size", "shape", "alpha"
base	Log base (default 10)

Value
