Matplotlib问题:为什么色条会删除我的xlabel？我怎样才能避免它呢？

import matplotlib.pyplot as plt
import numpy as np

# 创建数据
data = np.random.rand(10, 10)

# 创建图形和轴
fig, ax = plt.subplots()

# 绘制热图
im = ax.imshow(data)

# 添加色条，将其放置在右侧
cbar = fig.colorbar(im, ax=ax, orientation='vertical', pad=0.1)

# 添加xlabel
ax.set_xlabel('X Label')

# 显示图形
plt.show()

import matplotlib.pyplot as plt
import numpy as np

# 创建数据
data = np.random.rand(10, 10)

# 创建图形和轴
fig, ax = plt.subplots()

# 绘制热图
im = ax.imshow(data)

# 添加色条
cbar = fig.colorbar(im, ax=ax)

# 添加xlabel，并将其稍微上移
ax.set_xlabel('X Label', y=1.05)

# 显示图形
plt.show()

import matplotlib.pyplot as plt
import matplotlib.cm as cm
from mpl_toolkits.axes_grid1 import make_axes_locatable
import numpy as np

# 创建数据
data = np.random.rand(10, 10)

# 创建图形和轴
fig, ax = plt.subplots()

# 绘制热图
im = ax.imshow(data, cmap=cm.viridis)

# 使用make_axes_locatable调整布局
divider = make_axes_locatable(ax)
cax = divider.append_axes("right", size="5%", pad=0.05)

# 添加色条
cbar = plt.colorbar(im, cax=cax)

# 添加xlabel
ax.set_xlabel('X Label')

# 显示图形
plt.show()
