In hadley/ggplot1: Before there was ggplot2

Scale: colour (hcl) Scale continuous variables to hue, chroma and luminance components of colour

Description

This colour map is the most perceptually uniform. However, use multiple mappings with care. It is often a good idea to restrict the range of the hue, as shown in the example.

Usage

schcl(plot, name = "", to = list())

scfillhcl(plot, name = "", to = list())

Arguments

plot	plot
name	namen of the scale (used in the legend)
to	named list of target ranges (r.to, g.to, b.to, a.to)

Details

Note: alpha mappings only work with the Quartz and PDF devices.

Examples

p <- schcl(ggplot(reshape::tips, aes = list(x = total_bill, y = 1)))
ggjitter(p, list(h = tip))
ggjitter(p, list(c = tip))
ggjitter(p, list(l = tip))
