條形圖中的條與ggplot2

Question

是否有可能在R中用條形圖在ggplot2中繪製條形圖，如下圖所示。我想比較預期值和實際值，我想生成一個與下圖類似的圖。我已經提供了一些僞代碼：

library(tidyverse) 

df = data_frame(name = letters[1:10],profit = rnorm(mean = 100, sd = 20, n = 10), 
      target = profit + rnorm(mean = 10, sd = 10, n = 10)) 

    df %>% ggplot(aes(x = name, y = profit)) + geom_bar(stat = "identity") 

Answer 1

是的，它是可能的，看ggplot文檔

library(tidyverse) 

df = data_frame(name = letters[1:10],profit = rnorm(mean = 100, sd = 20, n = 10), 
       target = profit + rnorm(mean = 10, sd = 10, n = 10)) 

ggplot(df,aes(x=name,y=profit))+geom_bar(stat= "identity")+ 
geom_bar(aes(x= name,y=target),stat= "identity", width = 0.1,col = "green",fill="green")
