条形图上方的R geom_bar和facet_grid标签

Question

我试图让这个图表看起来更好，而且我坚持使用标签（在这种情况下为数字）。如何让它们显示在对应栏的顶部？注意它是facet_grid。 我有以下代码和输出：

ggplot(articles_europaoccidental_sex_count_unique_group, aes(Country, percentage)) + geom_bar(stat = "identity", position = "dodge", aes(fill=Gender)) + 
    facet_grid(~Propuesta) + geom_text(aes(label = round(percentage, 2)), position = position_dodge(width = 0.9), vjust = -1)

谢谢！

Answer 1

你几乎就在那里，只需将aes(fill=Gender)移到ggplot

内

library(tidyverse)
#Reproducible data set
test_mtcars <- mtcars %>% group_by(cyl,am, gear) %>% summarise(mean = mean(mpg))

ggplot(test_mtcars, aes(as.factor(cyl), mean, fill=as.factor(am))) + geom_bar(stat = "identity", position = "dodge") + 
facet_grid(~gear) + geom_text(aes(label = round(mean, 2)), position = position_dodge(width = 0.9), vjust = -1)
