如何使用 ggplot2 在具有离散 x 比例的分组箱线图之间移动刻度和标签？

  • 772

当然已经问过了，但我正在努力寻找适合我的情况的明确解决方案。

如何在分组的箱线图之间移动刻度（而不是以它们为中心）以定义小时间隔？

初始数据：
默认情况下，小时数以分组箱线图为中心

期望输出：
小时位于分组箱线图之间，即定义小时间隔

数据：

dat0 <- 
structure(list(group = c("A", "B", "A", "B", "A", "B", "A", "B", 
"A", "B", "A", "B", "A", "B", "A", "B", "A", "B", "A", "B", "A",

    hour通过将您的列更改为数字，我得到了以下结果。

    library(tidyverse)
dat0 <- 
  structure(list(group = c("A", "B", "A", "B", "A", "B", "A", "B",
