如何在Seaborn或Matplotplib中设置group colorbar xticks yticks

import seaborn as sns
import matplotlib.pyplot as plt

fig, ax = plt.subplots()

heatmap = sns.heatmap(data, ax=ax, cmap='coolwarm')
cbar = ax.collections[0].colorbar

ax.set_xticks([0.5, 1.5, 2.5])  # 设置x轴刻度位置
ax.set_yticks([0.5, 1.5, 2.5])  # 设置y轴刻度位置
ax.set_xticklabels(['A', 'B', 'C'])  # 设置x轴刻度标签
ax.set_yticklabels(['X', 'Y', 'Z'])  # 设置y轴刻度标签

import seaborn as sns
import matplotlib.pyplot as plt

# 创建数据
data = [[1, 2, 3], [4, 5, 6], [7, 8, 9]]

# 创建图形对象和子图对象
fig, ax = plt.subplots()

# 绘制图形并设置颜色条
heatmap = sns.heatmap(data, ax=ax, cmap='coolwarm')
cbar = ax.collections[0].colorbar

# 设置x轴和y轴的刻度标签
ax.set_xticks([0.5, 1.5, 2.5])
ax.set_yticks([0.5, 1.5, 2.5])
ax.set_xticklabels(['A', 'B', 'C'])
ax.set_yticklabels(['X', 'Y', 'Z'])

# 显示图形
plt.show()
