在堆叠的条形图中添加组之间的间距 [英] Add spacing between groups in a stacked bar plot

问题描述

假设我有一个带有分组条形图的条形图.酒吧有一个大的小组和多个非常小的小组.组标签在组上.为了提高可读性，我想在组之间引入一定的间距.

Suppose I have a bar plot with grouped bars. Bars have one large group and multiple very small groups. Group labels are on the groups. In order to increase readability, I want to introduce some amount of spacing between groups.

我使用以下代码和图像编辑器创建了一个示例图像.

I created an example image with the following code and an image editor.

library(ggplot2)
g <- ggplot(mpg, aes(class))
g + geom_bar(aes(fill = drv)) + theme_void()

到目前为止，我仅找到有关条形间距的答案.

So far, I have only found answers regarding spacing between bars.

推荐答案

使用白色边框.更改 size 以更改间隙的宽度.请注意，条形图的顶部和底部不再能准确反映出真实的基础价值.

Use a white border. Change the size to change the width of the gap. Note that the top and bottom of the bars no longer accurately reflect the true underlying values.

g + geom_bar(aes(fill = drv), color = 'white', size = 3) + theme_void()
