对x轴标签进行分组的重新图表

pip install matplotlib

import matplotlib.pyplot as plt

# 示例数据
categories = ['A', 'A', 'B', 'B', 'C', 'C']
subcategories = ['X', 'Y', 'X', 'Y', 'X', 'Y']
values = [10, 15, 20, 25, 30, 35]

# 创建一个新的图形
fig, ax = plt.subplots()

# 对x轴标签进行分组
x_ticks = []
x_labels = []
for category in set(categories):
    for subcategory in set(subcategories):
        x_ticks.append((category, subcategory))
        x_labels.append(f'{subcategory}-{category}')

# 绘制条形图
ax.bar(x_ticks, values)

# 设置x轴标签
ax.set_xticks(range(len(x_ticks)))
ax.set_xticklabels(x_labels)

# 添加标题和轴标签
ax.set_title('分组后的x轴标签')
ax.set_xlabel('类别-子类别')
ax.set_ylabel('值')

# 显示图形
plt.show()
