How to align the text horizontally in a bar plot created by using ggplot2 in R?
To align the text horizontally in a bar plot created by using ggplot2 in R, we can follow the below steps −
First of all, create a data frame.
Then, create the bar plot using ggplot2 with text displayed on each bar.
After that, create the same bar plot with text aligned horizontally.
Create the data frame
Let’s create a data frame as shown below −
Category<-c("First","Second","Third")
Count<-c(21,25,27)
df<-data.frame(Category,Count)
dfOn executing, the above script generates the below output(this output will vary on your system due to randomization) −
Output
Category Count 1 First 21 2 Second 25 3 Third 27
Create the bar plot with text displayed on each bar
Using annotate function to create the bar plot with text displayed on each bar −
Category<-c("First","Second","Third")
Count<-c(21,25,27)
df<-data.frame(Category,Count)
library(ggplot2)
ggplot(df,aes(Category,Count))+geom_bar(stat="identity")+scale_y_continuous(limits=c
(0,30))+annotate("text",x=1:3,y=c(21,25,27),label=c("I","II","III"))Output
Create the bar plot with text displayed on each bar horizontally
Using annotate function to create the bar plot with text displayed on each bar horizontally by setting y values to Inf −
Category<-c("First","Second","Third")
Count<-c(21,25,27)
df<-data.frame(Category,Count)
library(ggplot2)
ggplot(df,aes(Category,Count))+geom_bar(stat="identity")+scale_y_continuous(limits=c
(0,30))+annotate("text",x=1:3,y=Inf,vjust=1.5,label=c("I","II","III"))Output
