Horizontal Boxplots with Points using Seaborn in Python Last Updated : 23 Jul, 2025 Comments Improve Suggest changes Like Article Like Report Seaborn is an amazing visualization library for statistical graphics plotting in Python. It provides beautiful default styles and color palettes to make statistical plots more attractive. It is built on the top of matplotlib library and also closely integrated into the data structures from pandas.Seaborn aims to make visualization of the central part of exploring and understanding data. It provides dataset-oriented APIs, so that we can switch between different visual representations for the same variables for a better understanding of the dataset. Why horizontal Boxplots will be used instead of boxplots? They are useful when you have numerous groups with larger names. Boxplots works fine when we have a limited number of groups and short names of groups. But if we have longer titles they would overlap each other in boxplots, and it will get difficult to read the data and taking insights from the graph. Horizontal boxplots solve that problem very easily. Below is the step-by-step Approach to illustrate Horizontal Boxplots using Seaborn module:Import libraries Python3 # Import required modules import sklearn import numpy as np import matplotlib.pyplot as plt import pandas as pd import seaborn as sns Assign data Python3 # To avoid changing values everytime you run the cell np.random.seed(42) # Creating Data df = pd.DataFrame({ 'Ice-cream': np.random.normal(40, 15, 100), 'Chocolate': np.random.normal(60, 10, 100), 'Cakes': np.random.normal(80, 5, 100) }) # Display data print(df) Output: Mostly data we come across are in wide format. For example when you scrape a website. This data is in the wide form Convert the data into long-form by using pandas melt function. Python3 # Using melt dataframe for Converting data to long form data_df = df.melt(var_name='Dessert', value_name='Votes') # Data is in long form print(data_df.head()) Output: Plot this data into a boxplot. Python3 # Adjust size plt.figure(figsize=(8.3,6)) # Illustrate boxplot sns.boxplot(y="Dessert", x="Votes", data=data_df) Output: After plotting the data points into the boxplot. Strip plot can also be drawn on its own but it will complement while using with boxplot or violin plot. Python3 # It will create the data points inside the boxplot # Illustrating box plot sns.boxplot(y="Dessert", x="Votes", data=data_df) # Illustrating strip plot sns.stripplot(y="Dessert", x="Votes", color='black', alpha=0.3, data=data_df) Output: Changing our boxplot into the horizontal boxplot with data points by simply swapping the axes when we have numerous columns then names overlap with each other, so then we use a horizontal boxplot. Python3 # You can simply change into horizontal # boxplots by swapping x and y axes. # Illustrating box plot sns.boxplot(x="Dessert", y="Votes", data=data_df) # Illustrating strip plot sns.stripplot(x="Dessert", y="Votes", color='black', alpha=0.3, data=data_df) Output: Below is the complete program based on the above approach: Python3 # Import required modules import sklearn import numpy as np import matplotlib.pyplot as plt import pandas as pd import seaborn as sns # To avoid changing values everytime you run the cell np.random.seed(42) # Creating Data df = pd.DataFrame({ 'Ice-cream': np.random.normal(40, 15, 100), 'Chocolate': np.random.normal(60, 10, 100), 'Cakes': np.random.normal(80, 5, 100) }) # Using melt dataframe for Converting data to long form data_df = df.melt(var_name='Dessert', value_name='Votes') # Adjust size plt.figure(figsize=(8.3, 6)) # Assign title plt.title('Horizontal Boxplots with Points using Seaborn') # Illustrating box plot sns.boxplot(y="Dessert", x="Votes", data=data_df) Output: Comment More infoAdvertise with us Next Article Python Introduction P prachibindal2925 Follow Improve Article Tags : Python Python-Seaborn Practice Tags : python Similar Reads Python Tutorial - Learn Python Programming Language Python is one of the most popular programming languages.
