Python - 使用线图创建具有多列的时间序列图

要使用线图创建具有多列的时间序列图，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 中有多个列 −

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]
})

绘制多列时间序列图 −

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

# 创建 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]
})

# 多列时间序列图
sb.lineplot(x="Date_of_Purchase", y="Units Sold", data=dataFrame)
sb.lineplot(x="Date_of_Purchase", y="Units Returned", data=dataFrame)

# 设置标签
plt.ylabel("Units Returned Unites Sold")

plt.show()
