Python Pandas – 绘制包含所有列的分组水平条形图

要绘制包含所有列的分组水平条形图，请使用barh()创建条形图，并不设置a和y值。

首先，导入所需的库−

import pandas as pd
import matplotlib.pyplot as plt

创建一个包含3列的数据框−

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],
})

绘制包含所有列的分组水平条形图−

dataFrame.plot.barh(title='Car Specifications', color=("blue", "orange"))

示例

以下是完整的代码−

import pandas as pd
import matplotlib.pyplot as plt

# creating 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],
})

# plotting grouped Horizontal Bar Chart with all the columns
dataFrame.plot.barh(title='Car Specifications', color=("blue", "orange"))

# display the plotted Horizontal Bar Chart
plt.show()
