ggplot中的直方图

Question

我想绘制直方图。我还希望在y轴上具有密度而不是频率。

我能够创建直方图，但是y轴没有更改为密度。

你能帮我吗？

最好的问候， Dipen Bista

test=data.frame(c(0.17,0.39,0.24,0.24,0.17,0.42,0.33,0.25,0.36,0.26,0.24,0.16))
names(test) = 'ratio'
ggplot(data=test,aes(x=test$ratio,y=..density..)) + 
 geom_histogram(breaks=seq(0.1,0.5, by=0.1),
          col="black",
          fill="light gray",
          alpha=.8)+
          labs(title="Histogram of Length ratio")+
          labs(x='Angle',y='Density')+
          theme_bw()

Answer 1

library(ggplot2)
test = data.frame(c(0.17,0.39,0.24,0.24,0.17,0.42,0.33,0.25,0.36,0.26,0.24,0.16))
ggplot(test, aes(x = test$ratio)) + 
  geom_density()
