In dylan-stark/ggfocus: Focus, People!

Overview

ggfocus is an extension to ggplot2 that adds scales for emphasizing different features of a plot.

Installation

# install.packages("devtools")
devtools::install_github("dylan-stark/ggfocus")

Usage

Just add a scale_colour_focus() call to your plots at set the position (pos) argument to the position in the color scale that you want to emphasize. The selected position will retain it's color while all other positions will map to gray scale. Here's an example:

library(ggplot2)
library(ggfocus)

p3 <- ggplot(economics_long, aes(date, value01, colour = variable)) +
  geom_line()

p3

p3 + scale_colour_focus(3)
