Python Pandas - 绘制堆叠水平条形图

pythonserver side programmingprogramming更新于 2025/11/23 14:36:17

对于堆叠水平条形图，使用 barh() 创建条形图并设置参数"stacked" as True −

Stacked = True

首先，导入所需的库 −

import pandas as pd
import matplotlib.pyplot as plt

创建一个包含 3 列的 DataFrame −

dataFrame = pd.DataFrame({"Car": ['Bentley', 'Lexus', 'BMW', 'Mustang', 'Mercedes', 'Jaguar'],"Cubic_Capacity": [2000, 1800, 1500, 2500, 2200, 3000],"Reg_Price": [7000, 1500, 5000, 8000, 9000, 6000],
})

绘制所有列都为 − 的堆叠水平条形图

dataFrame.plot.barh(stacked=True, title='Car Specifications', color=("orange", "cyan"))

示例

以下是完整代码−

import pandas as pd
import matplotlib.pyplot as plt

# 创建 DataFrame
dataFrame = pd.DataFrame({"Car": ['Bentley', 'Lexus', 'BMW', 'Mustang', 'Mercedes', 'Jaguar'],"Cubic_Capacity": [2000, 1800, 1500, 2500, 2200, 3000],"Reg_Price": [7000, 1500, 5000, 8000, 9000, 6000],
})

# 绘制包含所有列的堆叠水平条形图
dataFrame.plot.barh(stacked=True, title='Car Specifications', color=("orange", "cyan"))

# 显示绘制的水平条形图
plt.show()
