Blend colour into a derived fill mapping

Note: this sets fill, not colour — colour is the value it reads from, fill is what it derives. Maps fill to a blended version of colour, evaluated after scale training via ggplot2::after_scale(). Attaches no scale itself — use scale_colour_fillblend_discrete() (or _continuous/_binned) for a ready-to-plot version that also scales colour.

Usage

aes_fillblend(blend = NULL)

Arguments

blend

A function that takes a colour vector and returns a blended colour vector.

Value

A ggplot2 mapping object (as returned by ggplot2::aes()).
