如何在小平面网格线之间放置分区 [英] How to place divisions between facet grid lines

问题描述

我使用ggplot和 facet_grid 来制作发布图。我不确定审稿人如何对标准的灰色背景做出反应，使用白色网格线，所以我正在准备和不准备。但是，当我使用 opts（panel.background = theme_blank（））时，显示器缺少标准背景给出的窗格区分。

代码

  ggplot（CO2，aes（conc））+ geom_density（）+ 
 facet_grid（Type〜Treatment）+ 
 opts（panel.background = theme_blank（））
  

当前结果

预期结果

解决方案

  last_plot（）+ theme_bw（）
  
 
 
 
 $ b $ $ $ $ $ $ $ last_plot（）+ $ 
 opts（panel.background = theme_rect（fill = NA，color =black））
  

从版本0.9.2开始， opts 已被被主题取代：

  last_plot（）+ 
主题（panel.background = element_rect（fill = NA，color =black））
  

I'm using ggplot with facet_grid to make a plot for publication. I'm not sure how the reviewers will react to the standard gray background with white grid lines and so I'm preparing with and without. However when I use opts(panel.background = theme_blank()) the display lacks the between panes discrimination that the standard background gives. what is the easiest way to add the between pane grid back (not that it was there but it was white against gray) that looks similar to my desired outcome below?

The Code

ggplot(CO2, aes(conc)) + geom_density() + 
    facet_grid(Type~Treatment) +
    opts(panel.background = theme_blank())

Current Outcome

Desired Outcome

Thank you in advance.

解决方案

This should do:

last_plot() + theme_bw()

or

last_plot() + 
   opts(panel.background = theme_rect(fill = NA, color = "black"))

Since version 0.9.2, opts has been replaced by theme:

last_plot() + 
   theme(panel.background = element_rect(fill = NA, color = "black"))
