ggplot在方格条形图中的计数旁边的方括号中显示份额

尝试这个

cat1 <- c("category1",
          "category2",
          "category3",
          "category4",
          "category5")
count <- c(12, 43, 31, 25, 11)

df <- data.frame(cat1, count)
df$share <- df$count / sum(df$count) * 100
df$label <- paste0(round(df$count, 2), " (", round(df$share, 1), "%)")
require(ggplot2)
#> Lade nötiges Paket: ggplot2

ggplot(df, aes(cat1, count)) +
  geom_bar(stat = "identity") +
  geom_text(aes(label = label), vjust = "bottom", size = 5)
