In this article, we are going to see how to create an area chart in seaborn using Python.

Area Charts are a great way to quickly and easily visualize things to show the average overtime on an area chart. Area charts are different from line graphs. Area charts are primarily used for the summation of quantitative data. however, the area between the line and the area chart is filled in with shading or color.

Area graph displays graphically quantitative data. It is based on the line chart. In both line graphs and area charts, data points are connected by line segment to show the values of a quantity at different points.

Example 1: Create Basic Area Chart in Seaborn

In this example, we are going to see how to create a basic area chart in seaborn.

Python3




import pandas as pd
import matplotlib.pyplot as plt
import seaborn as sns
  
#set seaborn style
sns.set_theme()
  
#define DataFrame
data = {'period': [1, 2],
                   'rohit': [10, 5],
                   'vikey': [5, 19],
                   }
  
df = pd.DataFrame(data)
  
#create area chart
plt.stackplot(df.period, df.rohit, df.vikey,
              labels=['rohit', 'vikey'])


Output:

Example 2: Create Custom Area Chart in Seaborn

In this example, we are going to see how to create an area chart by defining different colors in color_map=[] in seaborn.

Python3




import pandas as pd
import matplotlib.pyplot as plt
import seaborn as sns
  
# set seaborn style
sns.set_theme()
  
data = {'period': [1, 2, 3, 4, 5, 6, 7, 8],
                   'team_B': [15, 17, 17, 19, 22, 19, 19, 14],
                   'team_C': [21, 18, 20, 16, 16, 15, 19, 22]}
  
# define DataFrame
df = pd.DataFrame(data)
  
# define colors to use in chart
color_map = ['orange', 'pink']
  
#create area chart
plt.stackplot(df.period, df.team_B, df.team_C,
              labels=['Team B', 'Team C'],
              colors=color_map)


Output:

Example 3: Create Multiple Area Chart in Seaborn.

In this example, we are going to see how we can add create multiple area charts in a single subplot by defining different data with its different color in color_map=[] in seaborn.

Python3




import pandas as pd
import matplotlib.pyplot as plt
import seaborn as sns
  
# set seaborn style
sns.set_theme()
   
# define DataFrame
df = pd.DataFrame({'Class': [1, 2, 3, 4, 5, 6, 7, 8],
                   'sec_A': [20, 12, 9, 14, 18, 20, 15, 22],
                   'sec_B': [ 12, 5, 7, 7, 9, 9, 9, 4],
                   'sec_C': [11, 8, 5, 9, 12, 10, 6, 6]})
  
# define colors to use in chart
color_map = ['yellow', 'blue', 'black']
  
# create area chart
plt.stackplot(df.Class, df.sec_A, df.sec_B, df.sec_C,
              labels=['Sec A', 'Sec B', 'Sec C'],
              colors=color_map)


Output:
