ggplot堆积的条形图问题

Question

I have the following data

library(ggplot2)

d <- data.frame(
        Type= c("t1", "t2", "t3", "t4"),
        value= c(14000, 2500, 145, 900))

I want to create a horizontal stacked bar chart. I have the following code:

 ggplot(data = d, aes(x=Type, fill=value) ) + geom_bar() 

However this doesn't give me what I want. I just need one bar with the values stacked on top of one another. Any help would be really appreciated.

Thanks

Answer 1

If you have several x axis values ("t1", "t2", etc) the bars will not be stacked. They will be only if they share the same x value. That is solved with the dplyr pipe, that creates a temporary variable X .

Thanks to AntoniosK's comment for calling my atention to the OP's request for a horizontal bar.

library(ggplot2)
library(dplyr)


d %>%
  mutate(X = factor(1)) %>%
  ggplot(aes(x = X, y = value, fill = value) ) + 
    geom_bar(stat = "identity", width = 0.2) +
  coord_flip()
