在python中为多个子类别绘制多个直方图

import matplotlib.pyplot as plt

# 定义数据
data = {
    'Category 1': [1, 2, 3, 4, 5],
    'Category 2': [2, 4, 6, 8, 10],
    'Category 3': [3, 6, 9, 12, 15]
}

# 绘制直方图
fig, axs = plt.subplots(len(data), 1, figsize=(6, 6))

# 遍历每个子类别
for i, (category, values) in enumerate(data.items()):
    # 绘制直方图
    axs[i].hist(values, bins=5, alpha=0.5)
    axs[i].set_title(category)

# 设置图表标题和坐标轴标签
plt.suptitle('Histograms of Multiple Subcategories')
plt.xlabel('Value')
plt.ylabel('Frequency')

# 显示图表
plt.show()
