I was wondering if I could do that with ggplot. Is it possible to draw a clean, big arrow with ggplot2 and add it two the final multiplot?例如，我使用以下代码绘制图形：As an example I use this code to draw a plot:library(ggplot2)ggplot(diamonds, aes(clarity, fill=cut)) + geom_bar()对于该项目，我需要绘制三个图。结果应该是这样的：For the project I need to draw three plots like that. The result should be something like this:有没有人有办法解决吗？Does anyone have a solution? Many thanks in advance!推荐答案这里是一种方法：library(ggplot2)library(gridExtra)library(grid)library(png)download.file("https://www.wpclipart.com/signs_symbol/arrows/arrow_comic/Arrow_comic_right_gray.png", tf <- tempfile(fileext = ".png"), mode="wb")arrow <- rasterGrob(readPNG(tf))p <- ggplot(diamonds, aes(clarity, fill=cut)) + geom_bar()grid.arrange(p + guides(fill = "none"), arrow, p + guides(fill = "none"), arrow, p, ncol=5, widths=c(2/10, 1.75/10, 2/10, 1.75/10, 2.5/10)) 这篇关于如何制作ggplots链并在它们之间绘制箭头？的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持！ 上岸，阿里云！
