使用matplotlib绘制具有不同数据帧形状的条形图

import matplotlib.pyplot as plt
import numpy as np

data = np.array([[10, 15, 20, 25], [12, 18, 24, 30], [8, 16, 32, 40]])

labels = ['A', 'B', 'C', 'D']

fig, ax = plt.subplots()

# 水平条形图
ax.barh(labels, data[0], color='r', label='Data 1')

# 垂直条形图
ax.bar(labels, data[1], color='g', label='Data 2')

# 堆叠条形图
ax.bar(labels, data[2], color='b', label='Data 3', bottom=data[1])

# 添加图例
ax.legend()

# 添加标题和标签
ax.set_title('Bar Chart with Different Data Frame Shapes')
ax.set_xlabel('X Label')
ax.set_ylabel('Y Label')

# 显示图形
plt.show()
