How to create the stacked bar plot using ggplot2 in R with labels on the plot?

The creation of stacked bar plot using ggplot2 can be done with the help of position="stack" argument inside geom_bar function. If we want to create the stacked bar plot then geom_text function will be used with the same position argument and the aes to define the labels as shown in the below example.

Example

df<−data.frame(with(mtcars,table(cyl,gear)))
df

Output

cyl gear Freq
1 4 3 1
2 6 3 2
3 8 3 12
4 4 4 8
5 6 4 4
6 8 4 0
7 4 5 2
8 6 5 1
9 8 5 2

Loading ggplot2 package and creating the stacked bar plot −

Example

library(ggplot2)

Output

ggplot(df,aes(gear,fill=cyl))+geom_bar(aes(weight=Freq),position="stack")+geom_text(position="stack",aes(gear,Freq,label=cyl),size=5)

Output
