问题描述

我试图应用此解决方案（

I have tried to apply this solution (How can I change the size of the strip on facets in a ggplot?1) to change the size of the strip on facets in a ggplot, I have increase the height size

library(ggplot2)
library(gtable)

d <- ggplot(mtcars, aes(x=gear)) +
            geom_bar(aes(y=gear), stat="identity", position="dodge") +
            facet_wrap(~cyl)

g <- ggplotGrob(d)
g$heights[[3]] = unit(5,"in")

grid.newpage()
grid.draw(g)

This is what I get, it does only increase the space (white) on the top of the strip:

Why does it work differently?

解决方案

A simple solution is to specify the margins of your strip.text elements appropriately:

ggplot(mtcars, aes(x=gear)) +
  geom_bar(aes(y=gear), stat="identity", position="dodge") +
  facet_wrap(~cyl) +
  theme(strip.text.x = element_text(margin = margin(2,0,2,0, "cm")))
