好的,经过长时间的默读后,这是我的第一个问题。我正在尝试为分组条形图添加未高亮项目的相应标签。当我在geom_text前面插入gghighlight时,我得到了以下绘图:
library(tidyverse)
library(gghighlight)
df <- data.frame (group = c("A", "A", "B", "B", "C", "C"),
value = c("value_1", "value_2","value_1", "value_2","value_1", "value_2"),
mean = c(1.331, 1.931, 3.231, 3.331, 4.631, 3.331)
)
ggplot(data = df, aes(x = group, y = mean, fill = value)) +
geom_bar(stat = "identity", position = "dodge") +
gghighlight(group != "B",
label_key = group
) +
geom_text(aes(label = round(mean, digits = 2)),
stat= "identity",
vjust = -.5,
position = position_dodge(width = .9)
)
如果我将gghightlight移动到geom_text的后面,我会得到以下的图表:
ggplot(data = df, aes(x = group, y = mean, fill = value)) +
geom_bar(stat = "identity", position = "dodge") +
geom_text(aes(label = round(mean, digits = 2)),
stat= "identity",
vjust = -.5,
position = position_dodge(width = .9)
) +
gghighlight(group != "B",
label_key = group)
是否有一种方法可以像高亮的那些一样给未高亮的条形添加标签?
谢谢提前。

除了将某些列变为灰色(参见@TarJae的答案),还可以使它们变得透明(此帖子的关键部分来自:ggplot透明度对个别柱的影响):
subset_df <- df %>%
mutate(alpha.adj = as.factor(ifelse(group != "B", 1, 0.6)))
ggplot(data = subset_df, aes(x = group, y = mean, fill = value, alpha=factor(alpha.adj))) +
geom_bar(stat = "identity", position = "dodge") +
geom_text(aes(label = round(mean, digits = 2)),
stat= "identity",
vjust = -.5,
position = position_dodge(width = .9)
) +
scale_alpha_manual(values = c("0.6"=0.6, "1"=1), guide='none')
