Python - 使用折线图创建带有多个列的时间序列图


要在使用折线图的情况下创建带有多个列的时间序列图,请使用 lineplot()。首先导入所需的库 -

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

创建一个 DataFrame。我们的 DataFrame 包含多列 -

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]
})

为多列绘制时间序列图 -

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

示例

以下是代码 -

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

# creating DataFrame
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]
})

# time series plot for multiple columns
sb.lineplot(x="Date_of_Purchase", y="Units Sold", data=dataFrame)
sb.lineplot(x="Date_of_Purchase", y="Units Returned", data=dataFrame)

# set label
plt.ylabel("Units Returned Unites Sold")

plt.show()
