添加文字上的小的顶部躲避barplot使用GGPLOT2添加文字上的小的顶部躲避barplot使用G

我想绘制了两个不同的年躲过barplot并把收入数字上栏的顶部相应。 尝试颇有些建议，我发现在这里后，我仍然不能完全得到我想要的东西（所有的数字都显示在中间栏/栏的中间，而不是同样蔓延）。任何建议，将不胜感激。谢谢！

我的最新尝试

# Dodged barplot

  geom_bar(aes(fill = variable), position = "dodge", stat="identity") +
  xlab("County") + ylab("Revenue (Million USD)") +

  theme(axis.ticks.x = element_blank()) +
  theme(panel.background = element_rect(colour='dark grey')) +
  theme(strip.text.x = element_text(size = 20, face="bold"),
        strip.background = element_rect(colour="dark grey"))

# Add text on top of the bar
qbarplot_yr_1 + geom_text(data = censusData,
                          aes(x = County, y = value + 150, label = format(value, nsmall = 0, scientific = FALSE)), 
                          color="blue")

你需要闪避的文本值也是如此。尝试

qbarplot_yr_1 + geom_text(data = censusData,
         aes(x = County, group=variable, y = value + 150, 
         label = format(value, nsmall = 0, digits=1, scientific = FALSE)), 
         color="blue", position=position_dodge(.9), hjust=.5)

我们还需要group=所以它知道哪些值闪躲上。
