我想在ggplot2中增加面板背景的大小,以便扩展到轴标题,如下图所示:
我尝试使用element_rect,但没有成功。这是我到现在为止所得到的。
dat <- data.frame(x=2001:2017, y=rnorm(17,100))
ggplot2::ggplot(data=dat, ggplot2::aes(x=x, y=y)) +
ggplot2::geom_line(size=1.5) +
ggplot2::theme(panel.background=ggplot2::element_rect(fill="darkgrey"),
plot.background=ggplot2::element_rect(fill="lightgrey", color=NA)) +
ggplot2::ggtitle("Title of the plot")
任何帮助将不胜感激!
由于

你可以尝试
# first plot
p <- ggplot(data=dat, aes(x=x, y=y)) +
geom_line(size=1.5) +
theme(panel.background=element_rect(fill="darkgrey"),
plot.background=element_rect(fill="darkgrey"))
# blank plot
p1 <- ggplot(mtcars, aes(x = wt, y = mpg)) +
geom_blank() +
theme(plot.background=element_rect(fill="lightgrey"),
line = element_blank(),
axis.text = element_blank(),
axis.title = element_blank(),
plot.title = element_text(hjust = 0))
# plot with title
p2 <- p1 + ggtitle("Title of the plot", subtitle = "this is a sub")
# plot with figure text
p3 <- p1 + ggtitle("",subtitle = "this is a second sub")
# final plot
library(cowplot)
plot_grid(p2, p, p3, nrow = 3, rel_heights = c(10, 80, 10))
