r - Tornado 图/ggplot2 图表

Question

我在获取 this 时遇到了一些困难输出正确...

这是我迄今为止尝试过的:

示例数据:

dat <- data.frame(
variable=c("A","B","A","B"),
Level=c("Top-2","Top-2","Bottom-2","Bottom-2"),
value=c(.2,.3,-.2,-.3)
)

这是我迄今为止最接近的:

ggplot(dat, aes(variable, value, fill=Level)) + geom_bar(position="dodge")
## plots offset, as expected
ggplot(dat, aes(variable, value, fill=Level)) + geom_bar(position="stack") 
# or geom_bar(), default is stack but it overplots

Answer 1

自 2012 年起，ggplot 禁止 Error: Mapping a variable to y and also using stat="bin" 。解决办法是:

ggplot(dat, aes(variable, value, fill=Level)) +
    geom_bar(position="identity", stat="identity") 

如果您使用非对称示例，它也会非常有帮助，否则您怎么知道您是否没有查看镜像两次的顶级系列？!

dat <- data.frame(
  variable=c("A","B","A","B"),
  Level=c("Top-2","Top-2","Bottom-2","Bottom-2"),
  value=c(.8,.7,-.2,-.3)
  )
