如何使用matplotlib python在烛台图中只显示小时和分钟

import matplotlib.pyplot as plt
import matplotlib.dates as mdates
import datetime as dt

# 示例数据
timestamps = [
    dt.datetime(2022, 1, 1, 9, 30),
    dt.datetime(2022, 1, 1, 9, 31),
    dt.datetime(2022, 1, 1, 9, 32),
    # 其他时间戳...
]
opens = [100, 110, 105, ...]  # 开盘价
highs = [120, 115, 125, ...]  # 最高价
lows = [95, 100, 98, ...]  # 最低价
closes = [110, 105, 115, ...]  # 收盘价

fig, ax = plt.subplots()
ax.xaxis.set_major_locator(mdates.HourLocator(interval=1))  # 设置主要刻度为每小时
ax.xaxis.set_major_formatter(mdates.DateFormatter('%H:%M'))  # 设置刻度格式为小时和分钟

# 绘制烛台图
ax.plot(timestamps, opens, 'g-', label='Open')
ax.plot(timestamps, highs, 'r-', label='High')
ax.plot(timestamps, lows, 'b-', label='Low')
ax.plot(timestamps, closes, 'y-', label='Close')

# 设置图例和标题
ax.legend()
plt.title('Candlestick Chart')

# 自动调整x轴刻度标签的显示
fig.autofmt_xdate()

# 显示图形
plt.show()
