Get labels on the top of bars
In the below example, we will add geom_text() in the plot to get labels on top of each bar.
R
# Create sample data set.seed (5642) sample_data <- data.frame (name = c ( "Geek1" , "Geek2" , "Geek3" , "Geek4" , "Geeek5" ) , value = c (31,12,15,28,45)) # Load ggplot2 package library ( "ggplot2" ) # Create bar plot with labels plot<- ggplot (sample_data, aes (name,value)) + geom_bar (stat = "identity" )+ geom_text ( aes (label = signif (value)), nudge_y = 3) plot |

How to Add Labels Over Each Bar in Barplot in R?
In this article, we will see how to add labels over each bar in barplot in R Programming language.
To add labels on top of each bar in Barplot in R we use the geom_text() function of the ggplot2 package.
Syntax: plot+ geom_text(aes(label = value, nudge_y )
Parameters:
- value: value field of which labels have to display.
- nudge_y: distance shift in the vertical direction for the label
Creating a basic barplot with no labels on top of bars:
In the below example, we will create dataframe and then plot a barplot with this dataframe with no labels.
R
# Create sample data set.seed (5642) sample_data <- data.frame (name = c ( "Geek1" , "Geek2" , "Geek3" , "Geek4" , "Geeek5" ) , value = c (31,12,15,28,45)) # Load ggplot2 package library ( "ggplot2" ) # Create bar plot plot<- ggplot (sample_data, aes (name,value)) + geom_bar (stat = "identity" ) plot |
