ggplot2:如何以特定角度旋转图形? [英] ggplot2: How to rotate a graph in a specific angle?

问题描述

我想将ggplot2图旋转一个自己指定的角度.我发现了如何使用element_text(angle = 20) 旋转坐标轴文本 .我想对整个情节做些类似的事情.

I would like to rotate a ggplot2 graph by a self-specified angle. I found how to rotate the axis text with element_text(angle = 20). I would like to do something similar with the whole plot.

可复制的示例:

set.seed(123)

data_plot <- data.frame(x = sort(rnorm(1000)),
                        y = sort(rnorm(1000)))

ggplot(data_plot, aes(y, x)) +
    geom_line() # + theme(axis.title.x = element_text(angle = 20))

此图应旋转:

推荐答案

下面是一个粗略的主意，称您的情节p:

Here's a rough idea, calling your plot p:

library(grid)
pushViewport(viewport(name = "rotate", angle = 20, clip = "off", width = 0.7, height = 0.7))
print(p, vp = "rotate")

您可能想根据自己想要的角度和纵横比来定制width和height.

You'll probably want to tailor the width and height to the angle and aspect ratio you want.
