R 如何在ggplot内改变binwidth？

我正在用ggplot做柱状图

p <- ggplot(TotCalc, aes(x=x,y=100*(..count../sum(..count..)))) + 
    xlab(xlabel) + ylab(ylabel) +
    geom_histogram(colour = "darkblue", fill = "white", binwidth=500)

我该怎么做呢？

休息一下怎么样

x <- rnorm(100)
ggplot(NULL, aes(x)) + 
  geom_histogram(breaks = c(-5, -2, 0, 5), 
  position = "identity", colour = "black", fill = "white")

---

x使用
breaks
和
position=“dodge”

例如：

没有您的数据，但对于您的示例：

p <- ggplot(TotCalc, aes(x=x,y=100*(..count../sum(..count..)))) +
     xlab(xlabel) + ylab(ylabel) +
    geom_histogram(colour = "darkblue", fill = "white", breaks=cumsum(c(180,100,110,160,200,250,1000,3000)), position="dodge")

p
ggplot(mtcars,aes(x=hp))+geom_histogram(breaks=c(50,100,200,350),position="dodge")

p <- ggplot(TotCalc, aes(x=x,y=100*(..count../sum(..count..)))) +
     xlab(xlabel) + ylab(ylabel) +
    geom_histogram(colour = "darkblue", fill = "white", breaks=cumsum(c(180,100,110,160,200,250,1000,3000)), position="dodge")
