Creates a new scale "slot". Geoms added to a plot after this function will use a new scale definition.

new_scale(new_aes)

new_scale_fill()

new_scale_color()

new_scale_colour()

Arguments

new_aes

A string with the name of the aesthetic for which a new scale will be created.

Details

new_scale_color(), new_scale_colour() and new_scale_fill() are just aliases to new_scale("color"), etc...

Examples

library(ggplot2) # Equivalent to melt(volcano), but we don't want to depend on reshape2 topography <- expand.grid(x = 1:nrow(volcano), y = 1:ncol(volcano)) topography$z <- c(volcano) # point measurements of something at a few locations measurements <- data.frame(x = runif(30, 1, 80), y = runif(30, 1, 60), thing = rnorm(30)) ggplot(mapping = aes(x, y)) + geom_contour(data = topography, aes(z = z, color = stat(level))) + # Color scale for topography scale_color_viridis_c(option = "D") + # geoms below will use another color scale new_scale_color() + geom_point(data = measurements, size = 3, aes(color = thing)) + # Color scale applied to geoms added after new_scale_color() scale_color_viridis_c(option = "A")
