ggplot2, facet_grid, free scales?
In the following example, how do I get the y-axis limits to scale according to the data in each panel?
mt <- ggplot(mtcars, aes(mpg, wt, colour = factor(cyl))) + geom_point()
Neither of these will do it:
mt + facet_grid(. ~ cyl, scales="free")
mt + facet_grid(. ~ cyl, scales="free_y")
Perhaps it's because you have only one y axis, using your way. Did you try something like this?
mt + facet_grid(cyl ~ ., scales="free")
You can't. See here
You can use facet_wrap instead, which will 'free' both axes
Hopefully, this helps.
mt + facet_wrap(. ~ cyl, scales="free_y")
