ggplot2，facet_grid，自由缩放？ [英] ggplot2, facet_grid, free scales?

问题描述

在下面的例子中，我如何根据每个面板中的数据获得y轴限制？

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() 

这两种都不会：

Neither of these will do it:

mt + facet_grid(. ~ cyl, scales="free")
mt + facet_grid(. ~ cyl, scales="free_y")

推荐答案

也许这是因为你只有一个y轴，用你的方式。

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")
