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.
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..
You can also adjust the color, , filled color, statistics (mean, etc) in violin plots.
Also a horizontal violin plot is available.
