问题描述

通常情况下,要尽量减少情节中的墨水。我有一个多面情节( facet_wrap ),并且希望删除尽可能多的墨迹,同时保持可读性。我已经按照我的意愿设置了它,除非x和y轴不存在于小平面(子图)中,除非在最左边或底部。有了这么多的墨水,我相信眼睛需要这些线索,并且要求如何将x和y轴放在 facet_wrap 内的所有图中。下面是我的代码到目前为止,当前的输出和期望的输出(红线是所需的加入):

  library( ggplot);库(网格)

ggplot(mtcars,aes(mpg,hp))+
geom_point()+
facet_wrap(〜carb)+
主题(面板。 grid = element_blank(),
panel.background = element_rect(fill =white,color =black),
panel.border = element_rect(fill = NA,color =white),
axis.line = element_line(),
strip.background = element_blank(),
panel.margin = unit(2,lines))

解决方案

最简单的方法是在每个绘图面板中添加细分,

  ggplot(mtcars,aes(mpg,hp))+ 
geom_point( )+
facet_wrap(〜carb)+
theme_minimal()+
annotate(segment ,x = -Inf,xend = Inf,y = -Inf,yend = -Inf)+
annotate(segment,x = -Inf,xend = -Inf,y = -Inf,yend = Inf )

It is often desirable to minimize ink in a plot. I have a faceted plot (facet_wrap) and would like to remove as much ink as possible yet maintain readability. I have set it up as I'd like except the x and y axis is not present for the facets (subplots) unless on the far left or bottom. With so much ink removed I believe the eye needs these cues and am asking how to put the x and y axis in all plots within a facet_wrap. Below is my code thus far, the current output and the deired output (red lines are the desired add in):

library(ggplot); library(grid)

ggplot(mtcars, aes(mpg, hp)) +
    geom_point() +
    facet_wrap(~carb) +
    theme(panel.grid = element_blank(),
        panel.background = element_rect(fill = "white", colour = "black"),
        panel.border = element_rect(fill = NA, colour = "white"),
        axis.line = element_line(),
        strip.background = element_blank(),
        panel.margin = unit(2, "lines"))

Desired Plot

解决方案

easiest way would be to add segments in each plot panel,

ggplot(mtcars, aes(mpg, hp)) +
  geom_point() +
  facet_wrap(~carb) +
  theme_minimal() +
  annotate("segment", x=-Inf, xend=Inf, y=-Inf, yend=-Inf)+
  annotate("segment", x=-Inf, xend=-Inf, y=-Inf, yend=Inf)
