ggplot .

dat <- read.table(text = "sample Types Value
sample1 A   -36

library(ggplot2)    
px <- ggplot(data = dat , aes(x = Types , y = Value , Colour = Types ))
px + geom_bar(stat = "identity" ,color = "#FFFFFF" , fill = "dodgerblue3") +
  geom_text(aes(label=Value), position=position_dodge(width=0.9), hjust= -.25,vjust=0.25 ,size =3.5 , angle = 90)

geom_text y = Value + 2 * sign(Value)

library(ggplot2)
ggplot(dat, aes(Types, Value)) + 
    geom_bar(stat = "identity" ,color = "#FFFFFF" , fill = "dodgerblue3") +
    geom_text(aes(y = Value + 2 * sign(Value), label = Value), 
              position = position_dodge(width = 0.9), 
              size = 3.5 , angle = 90)

我在绘图上做的另一个带有轻微视觉调整的绘图:

ggplot(dat, aes(Types, Value)) + 
    geom_bar(stat = "identity", color = "black" , fill = "grey", 
             size = 0.7, width = 0.9) +
    geom_text(aes(y = Value + 2 * sign(Value), label = Value), 
              position = position_dodge(width = 0.9), 
              size = 5) +
    theme_classic() +
    theme(axis.text.x = element_text(size = 12),
          axis.title = element_text(size = 20),
          axis.text.y = element_blank(),
          axis.line = element_blank(),
          axis.ticks = element_blank())
