导入日期时间并在绘图中转换为分钟

import datetime
import matplotlib.pyplot as plt

data = [
    "2022-01-01 12:00:00",
    "2022-01-01 12:05:00",
    "2022-01-01 12:10:00",
    # 添加更多日期时间数据
]

minutes = []
base_time = datetime.datetime.strptime("2022-01-01 00:00:00", "%Y-%m-%d %H:%M:%S")  # 基准时间，可以根据实际情况调整

for dt_str in data:
    dt = datetime.datetime.strptime(dt_str, "%Y-%m-%d %H:%M:%S")
    diff = dt - base_time
    minutes.append(diff.total_seconds() / 60)

plt.plot(minutes)  # 绘制折线图
plt.xlabel("Index")
plt.ylabel("Minutes")
plt.title("Conversion of Date Time to Minutes")
plt.show()
