Horizontal Violin Plot

To convert a normal violin plot to a horizontal violin plot we add the coord_flip() function to the ggplot() function. This flips the coordinate axis of the plot and converts any ggplot2 plot into a horizontal plot. 

Syntax: plot+ coord_flip()

Here, is a horizontal violin plot made using the coord_flip() function. 

 
Output: 

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.
