如何仅标记特定的x-ticks matplotlib？

import matplotlib.pyplot as plt

# 获取当前的刻度位置和标签
x_ticks, x_labels = plt.xticks()

# 修改特定刻度的标签
x_labels[2] = 'New Label'

# 应用修改后的刻度位置和标签
plt.xticks(x_ticks, x_labels)

import matplotlib.pyplot as plt

# 生成示例数据
x = [1, 2, 3, 4, 5]
y = [2, 4, 6, 8, 10]

# 绘制折线图
plt.plot(x, y)

# 获取当前的刻度位置和标签
x_ticks, x_labels = plt.xticks()

# 修改特定刻度的标签
x_labels[2] = 'New Label'

# 应用修改后的刻度位置和标签
plt.xticks(x_ticks, x_labels)

# 显示图形
plt.show()
