使用一致的每小时标记在python中绘制时间序列

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

import datetime

# 生成时间序列数据
start_time = datetime.datetime(2022, 1, 1, 0, 0, 0)
end_time = datetime.datetime(2022, 1, 1, 23, 0, 0)
time_interval = datetime.timedelta(hours=1)

timestamps = []
values = []

current_time = start_time
while current_time <= end_time:
    timestamps.append(current_time)
    values.append(0)  # 假设每小时的值为0
    current_time += time_interval

# 创建图表
fig, ax = plt.subplots()

# 绘制时间序列
ax.plot(timestamps, values)

# 设置x轴的日期刻度定位器和格式化器
ax.xaxis.set_major_locator(mdates.HourLocator(interval=1))
ax.xaxis.set_major_formatter(mdates.DateFormatter('%Y-%m-%d %H:%M:%S'))

# 设置x轴标签的旋转角度
plt.xticks(rotation=45)

# 显示图表
plt.show()
