Color scales built from the equal-lightness color scales of The
Economist visual styleguide (v1.2, 4 May 2017); see
economist_seq_pal().
The _c scales are continuous; the _ordinal scales are
discrete, for ordered factors. See scale_colour_economist()
for the unordered categorical scales.
Usage
scale_colour_economist_c(hue = "blue", ..., guide = "colourbar")
scale_color_economist_c(hue = "blue", ..., guide = "colourbar")
scale_fill_economist_c(hue = "blue", ..., guide = "colourbar")
scale_colour_economist_ordinal(hue = "blue", ...)
scale_color_economist_ordinal(hue = "blue", ...)
scale_fill_economist_ordinal(hue = "blue", ...)Arguments
- hue
