当我在同一张图中绘制函数和柱状图时，轴有问题

import matplotlib.pyplot as plt
import numpy as np

# 示例数据
x = np.linspace(0, 10, 100)
y = np.sin(x)
bars_x = np.arange(10)
bars_y = np.random.randint(-1, 1, size=10)

# 创建图表
fig, ax = plt.subplots()

# 绘制函数曲线
ax.plot(x, y, label='Sine Function')

# 绘制柱状图
ax.bar(bars_x, bars_y, alpha=0.5, label='Random Bars')

# 设置坐标轴范围
ax.set_xlim([0, 10])
ax.set_ylim([-2, 2])

# 调整刻度和标签
ax.xaxis.set_ticks(np.arange(0, 11, 2))
ax.yaxis.set_ticks(np.arange(-2, 3, 1))

# 添加图例
ax.legend()

plt.show()

ax.set_xticklabels(ax.get_xticks(), rotation=45)

ax2 = ax.twinx()
ax2.bar(bars_x, bars_y*10, alpha=0.5, color='orange', label='Scaled Bars')
ax2.set_ylim([-20, 20])
