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 )
- 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.
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.
Multiple labels on the top of bars
By adjusting the nudge_y values you can add multiple label on top of bars.
