根据每组的值填写堆积百分比条形图，R

import matplotlib.pyplot as plt
import numpy as np

# 假设我们有以下数据
categories = ['Category 1', 'Category 2', 'Category 3']
sub_categories = ['Sub A', 'Sub B', 'Sub C']
values = np.array([
    [30, 20, 50],  # Category 1 的值
    [10, 40, 50],  # Category 2 的值
    [25, 25, 50]   # Category 3 的值
])

# 创建堆积条形图
fig, ax = plt.subplots()
ax.bar(categories, values[:,0], label=sub_categories[0])
for i in range(1, len(sub_categories)):
    ax.bar(categories, values[:,i], bottom=np.sum(values[:,:i], axis=1), label=sub_categories[i])

# 添加图例
ax.legend()

# 添加百分比标签
for i in range(len(categories)):
    for j in range(len(sub_categories)):
        percentage = values[i,j] / np.sum(values[i,:]) * 100
        ax.text(i, np.sum(values[:i,j]) + values[i,j]/2, f'{percentage:.1f}%', ha='center', va='center')

# 设置标题和标签
ax.set_title('Stacked Percentage Bar Chart')
ax.set_xlabel('Categories')
ax.set_ylabel('Percentage')

plt.show()
