is a simple replacement of geom_line()
library(ggshadow) ggplot(economics_long, aes(date, value01, colour = variable)) + geom_shadowline()
It is possible to draw lines with varying colors, and it is also possible to change the color, alpha and size of the shadow using shadowcolor
, shadowsize
and shadowalpha
.
library(ggshadow) ggplot(economics_long, aes(date, value01, group = variable, colour=value01, shadowcolor='grey', shadowalpha=0.5, shadowsize=5*(1-value01))) + geom_shadowline()
geom_shadowpoint()
Example using geom_shadowpoint()
.
ggplot(mtcars, aes(wt, mpg)) + geom_shadowpoint(aes( color = carb, shadowcolour = ifelse(vs == 1, 'red', 'blue') ))
