Adding box plot in violin plot
Adding a box plot in the violin plot we will use the geom_boxplot function which helps to make a box plot.
R
# Load library ggplot2library(ggplot2)# Basic violin plot# diamonds dataframe has been used here# diamonds dataframe is provided by R language natively.ggplot(diamonds, aes(x = cut, y = price)) + # geom_violin() function is used to plot violin plot geom_violin() + # Add geom_boxplot() to include box plot geom_boxplot(width = 0.2, fill = "white", color = "black") |
Output:
Violin Plots with ggplot2 in R
How To Make Violin Plots with ggplot2 in R?
Violin plots help us to visualize numerical variables from one or more categories. They are similar to box plots in the way they show a numerical distribution using five summary-level statistics. But violin plots also have the density information of the numerical variables. It allows visualizing the distribution of several categories by displaying their densities.
In this article, we will discuss how to plot a violin plot with the help of the ggplot2 library in R Programming Language. To plot a violin plot using the ggplot2 package we use the geom_violin() function.
Syntax: ggplot( dataframe, aes( x, y, fill, color)) + geom_violin()
Parameters:
- dataframe: determines the dataset used in the plot.
- fill: determines the color of background of interior of the plot.
- color: determines the color of boundary of plot.
