Theme similar to the default look of charts in Apple Numbers.
Details
The values used here are those in the chart-style-default style of
the theme stylesheet that ships inside Numbers: no chart background fill,
gridlines in the value direction only, a border along the bottom of the
chart but not the other three sides, and no tick marks.
Examples
library("ggplot2")
p <- ggplot(mtcars) +
geom_point(aes(x = wt, y = mpg, colour = factor(gear))) +
facet_wrap(~am)
p + theme_numbers() + scale_color_numbers()
