我很难弄清楚如何从
strip.text
旋转 theme
中的 ggplot2
属性。我正在使用 R 版本 3.4.2 和 ggplot2 版本 2.2.1。
以下是 MWE 的数据。
> dput(dd)
structure(list(type = structure(c(1L, 2L, 3L, 4L, 1L, 2L, 3L,
4L, 1L, 2L, 3L, 4L, 1L, 2L, 3L, 4L, 1L, 2L, 3L, 4L), .Label = c("blossum",
"happy", "rugged", "theatre"), class = "factor"), min = c(3,
2, 4, 6, 3, 2, 4, 6, 3, 2, 4, 6, 3, 2, 4, 6, 3, 2, 4, 6), max = c(8,
3, 7, 9, 8, 3, 7, 9, 8, 3, 7, 9, 8, 3, 7, 9, 8, 3, 7, 9), avg = c(5,
1, 3, 3, 5, 1, 3, 3, 5, 1, 3, 3, 5, 1, 3, 3, 5, 1, 3, 3), y = c(1L,
1L, 1L, 1L, 2L, 2L, 2L, 2L, 3L, 3L, 3L, 3L, 4L, 4L, 4L, 4L, 5L,
5L, 5L, 5L)), .Names = c("type", "min", "max", "avg", "y"), row.names = c(NA,
20L), class = "data.frame")
现在使用
element_text()
属性时,我可以为 strip.text
着色,但无法更改角度。我希望条带(面)名称在左侧水平运行。这是代码:
library(ggplot2)
ggplot(dd, aes(x = y, ymin = min, ymax = max, y = avg)) +
facet_wrap(~ type, ncol = 1, strip.position = "left") +
geom_ribbon(aes(x = y, ymin = min, ymax = max),
color='black', fill='gray70') + coord_flip() +
theme(strip.background = element_blank(),
strip.text = element_text(angle=90, color='blue4'),
axis.title.y = element_blank(),
axis.text.y = element_blank(),
axis.ticks.y = element_blank(),
axis.line.y = element_blank())
然而,这不是我想要的,因为当角度改变时,它们没有区别
strip.text = element_blank(angle=90, color='blue4')
。
没关系,我通过使用
strip.text.y = element_text(angle = 180)
弄清楚了。不知道为什么 strip.text
单独不起作用。
立即使用
strip.text.y.left
。angle = 0
作为参数。
ggplot(dd, aes(x = y, ymin = min, ymax = max, y = avg)) +
facet_wrap(~ type, ncol = 1, strip.position = "left") +
geom_ribbon(aes(x = y, ymin = min, ymax = max),
color='black', fill='gray70') + coord_flip() +
theme(
strip.background = element_blank(),
strip.text.y.left = element_text(angle = 0, color = 'blue4'), #THE LINE THAT IS EDITED
axis.title.y = element_blank(),
axis.text.y = element_blank(),
axis.ticks.y = element_blank(),
axis.line.y = element_blank())
答案取自此评论
ggplot(dd, aes(x = y, ymin = min, ymax = max, y = avg)) +
facet_wrap(~ type, ncol = 1, strip.position = "left") +
geom_ribbon(aes(x = y, ymin = min, ymax = max),
color='black', fill='gray70') + coord_flip() +
theme(strip.background = element_blank(),
strip.text.y = element_text(angle=180, color='blue4'),
axis.title.y = element_blank(),
axis.text.y = element_blank(),
axis.ticks.y = element_blank(),
axis.line.y = element_blank()
)
