Title and Subtitle With Different Color
To change the color of Title and Subtitle, We simply add a color parameter to element_text() function. All others are the same as the above implementation. Here we set the value of the color of title as green and the value of subtitle as red.
R
library(ggplot2) data <- data.frame( Name = c("A", "B", "C", "D", "E") , Value = c(3, 12, 5, 18, 45) ) # Create a BarPlot with title # and subtitle with different colors. ggplot(data, aes(x = Name, y = Value)) + geom_bar(stat = "identity", fill = "green")+ labs(title = "Title For Barplot", subtitle = "This is Subtitle" )+ theme(plot.title = element_text(size = 30, color = "green"), plot.subtitle = element_text(size = 20, color = "red") ) |
Output:

ggplot2 – Title and Subtitle with Different Size and Color in R
A Title and the subtitle to a plot give a piece of information about the graph that what the graph actually wants to represent. This article describes how to add a Title and Subtitle with Different Sizes and Colors using ggplot2 in R Programming.
To add a Title and Subtitle within a plot, first, we have to import ggplot2 library using library() function. If you have not installed yet, you can simply install it by writing a command install.packages(“ggplot2”) in R Console.
library(ggplot2)
Consider the following data for the example:
data <- data.frame(
name=c("A","B","C","D","E") ,
value=c(3,12,5,18,45)
)
| Name | Value | |
|---|---|---|
| 1 | A | 3 |
| 2 | B | 12 |
| 3 | C | 5 |
| 4 | D | 18 |
| 5 | E | 45 |
Creating a Plot using ggplot() function with the value of X-axis as Name and Y-axis as Value and make it a barplot using geom_bar() function of the ggplot2 library. Here we use the fill parameter to geom_bar() function to color the bars of the plots.
R
# Load Package library(ggplot2) # Create a Data data <- data.frame( Name=c("A", "B", "C", "D", "E") , Value=c(3, 12, 5, 18, 45) ) # Create a Simple BarPlot with green color. ggplot(data, aes(x = Name, y = Value)) + geom_bar(stat = "identity", fill = "green") |
