Matplotlib is a plotting library utilized in python. The sides of the "violins" in a violin plot corresponds to a kernel density estimation (kind of like a histogram) flipped vertically. This example demonstrates how to fully customize violin plots. Let us make violin plot using Matplotlib's violinplot() function. Step 1: Import required libraries # importing matplotlib import matplotlib.pyplot as plt # importing numpy library to get 2 samples of normal distributions import numpy as np Unlike a box plot, in which all of the plot components correspond to actual datapoints, the violin plot features a kernel density estimation of the underlying distribution. From simple to complex visualizations, it's the go-to library for most. This is where the data is fed to the function. positions: array-like, default = [1, 2, , n]. The provided data values to the ax.boxplot () method can be a Numpy array or Python . Let's say the following is our dataset in the form of a CSV file Cricketers2 . To create a violin plot, import the matplotlib.pyplot module and call the method violinplot () function by passing the data as sequences.
