You can use the following basic syntax to create a horizontal barplot in seaborn:
sns.barplot(x=df.values_var, y=df.group_var, orient='h')
The orient=’h’ argument tells seaborn to orient the bars horizontally instead of the default vertical.
The following example shows how to use this syntax in practice.
Example: How to Create a Horizontal Barplot in Seaborn
Suppose we have the following pandas DataFrame that contains information about the total sales made by various employees at a company:
import pandas as pd
#create DataFrame
df = pd.DataFrame({'employee': ['Andy', 'Bert', 'Chad', 'Doug', 'Eric', 'Frank'],
'sales': [22, 14, 9, 7, 29, 20]})
#view DataFrame
print(df)
employee sales
0 Andy 22
1 Bert 14
2 Chad 9
3 Doug 7
4 Eric 29
5 Frank 20
We can use the following syntax to create a horizontal barplot to visualize the sales by each employee:
import seaborn as sns #create horizontal barplot sns.barplot(x=df.sales, y=df.employee, orient='h')
The x-axis displays the sales made by each employee and the y-axis shows the names of the employees.
Note that we can also specify the colors of the bars and add a custom title with axis labels:
import matplotlib.pyplot as plt import seaborn as sns #create horizontal bar chart sns.barplot(x=df.sales, y=df.employee, color='steelblue', orient='h') #add plot title plt.title('Total Sales by Employee', fontsize=16) #add axis labels plt.xlabel('Total Sales') plt.ylabel('Employee Name')
The bars in the plot now each have the same color and we’ve added an overall plot title and axis labels to make the plot easier to read.
Note: If you have trouble importing seaborn in a Jupyter notebook, you may first need to run the command %pip install seaborn.
