Python - Tạo Time Series Plot nhiều cột bằng Line Plot

Tạo Time Series Plot nhiều cột dùng lineplot() nhiều lần.

Nhập thư viện:

import seaborn as sb 
import pandas as pd 
import matplotlib.pyplot as plt

Tạo DataFrame nhiều cột:

dataFrame = pd.DataFrame({'Date_of_Purchase': ['2018-07-25', '2018-10-25', '2019-01-25', '2019-05-25', '2019-08-25', '2020-09-25', '2021-03-25'],
    'Units Sold': [98, 77, 51, 70, 70, 87, 76],
    'Units Returned': [60, 50, 40, 57, 62, 51, 60]})

Vẽ 2 lineplot:

sb.lineplot(x="Date_of_Purchase", y="Units Sold", data=dataFrame)
sb.lineplot(x="Date_of_Purchase", y="Units Returned", data=dataFrame)

Ví dụ

import seaborn as sb 
import pandas as pd 
import matplotlib.pyplot as plt 
dataFrame = pd.DataFrame({'Date_of_Purchase': ['2018-07-25', '2018-10-25', '2019-01-25', '2019-05-25', '2019-08-25', '2020-09-25', '2021-03-25'],
    'Units Sold': [98, 77, 51, 70, 70, 87, 76],
    'Units Returned': [60, 50, 40, 57, 62, 51, 60]}) 
sb.lineplot(x="Date_of_Purchase", y="Units Sold", data=dataFrame)
sb.lineplot(x="Date_of_Purchase", y="Units Returned", data=dataFrame)
plt.ylabel("Units Returned Units Sold")
plt.show()
