scale_fill_highlight(highlight, color = "#3B0A45", fade = "#cccccc", ...)

scale_colour_highlight(highlight, color = "#3B0A45", fade = "#cccccc", ...)

scale_color_highlight(highlight, color = "#3B0A45", fade = "#cccccc", ...)

Arguments

highlight

Character. The name of the category level to highlight.

color

Character. The highlight color. Default is "#3B0A45" (solaris purple).

fade

...

Additional arguments passed to discrete_scale.

Value

A ggplot2 scale object.

Details

The highlight level receives color (default solaris purple, "#3B0A45") while all other levels receive fade (default light grey, "#cccccc").
