无法在Seaborn带状图中使用'x‘和'+’标记

import matplotlib.pyplot as plt
import numpy as np

# 创建随机数据
np.random.seed(42)
data1 = np.random.normal(0, 1, 100)
data2 = np.random.normal(2, 1, 100)
data3 = np.random.normal(4, 1, 100)

# 绘制带状图
fig, ax = plt.subplots()
ax.scatter(np.zeros_like(data1), data1, marker='x', label='Data 1')
ax.scatter(np.ones_like(data2), data2, marker='+', label='Data 2')
ax.scatter(2 * np.ones_like(data3), data3, marker='x', label='Data 3')

# 设置x轴标签
ax.set_xticks([0, 1, 2])
ax.set_xticklabels(['Data 1', 'Data 2', 'Data 3'])

# 设置图例
ax.legend()

# 显示图表
plt.show()
