import matplotlib.pyplot as plt
from datetime import datetime

# 读取数据
timestamps = []
values = []
with open('data.txt', 'r') as file:
    for line in file:
        timestamp_str, value_str = line.strip().split(', ')
        timestamps.append(datetime.strptime(timestamp_str, '%Y-%m-%d %H:%M:%S'))
        values.append(float(value_str))

# 创建折线图
plt.figure(figsize=(10, 5))
plt.plot(timestamps, values, marker='o')
plt.title('Time Series Data Visualization')
plt.xlabel('Timestamp')
plt.ylabel('Value')
plt.grid(True)
plt.xticks(rotation=45)
plt.tight_layout()  # 调整布局以防止标签重叠

# 显示图表
plt.show()

plt.rcParams['font.sans-serif'] = ['SimHei']  # 设置中文字体为黑体

pip install matplotlib
