Description
Shadow and Glow Geoms for 'ggplot2'.
Description
A collection of Geoms for R's 'ggplot2' library. geom_shadowpath(), geom_shadowline(), geom_shadowstep() and geom_shadowpoint() functions draw a shadow below lines to make busy plots more aesthetically pleasing. geom_glowpath(), geom_glowline(), geom_glowstep() and geom_glowpoint() add a neon glow around lines to get a steampunk style.

:chart: Example
With ggshadow
library(ggplot2)
library(ggshadow)
ggplot(economics_long, aes(date, value01, colour = variable)) + geom_shadowline()
Without ggshadow
library(ggplot2)
ggplot(economics_long, aes(date, value01, colour = variable)) + geom_line()
ggshadow supports varying the line color
library(ggshadow)
library(ggplot2)
ggplot(economics_long,
aes(date, value01,
group = variable,
colour=value01,
shadowcolor='grey',
shadowalpha=0.5,
shadowsize=5*(1-value01))) +
geom_shadowline()
ggshadow also provides a Neon glow style
ggplot(economics_long, aes(date, value01, color = variable)) +
geom_glowline() + guides(color='none') +
theme(plot.background = element_rect(fill = "#190132"),
panel.background = element_rect(fill = "#190132"))
Neon glow points
ggplot(mtcars, aes(wt, mpg)) +
geom_glowpoint(color='yellow') +
guides(color='none') +
theme(plot.background = element_rect(fill = "#190132"),
panel.background = element_rect(fill = "#190132"))
Adding a fill below the neon glow line
library(dplyr)
ggplot(filter( economics_long, variable %in% c('pop', 'unemploy') ),
aes(date, value01-0.5, color = variable, fill=variable)) +
geom_glowline() + guides(color='none', shadowcolour='none', fill='none') +
theme(plot.background = element_rect(fill = "#190132"),
panel.background = element_rect(fill = "#190132"))
