在Python /R中绘制两个不同时间戳中的两个变量

import pandas as pd
import matplotlib.pyplot as plt

# 假设我们有两个时间戳和对应的变量值
data = {
    'timestamp': ['2023-01-01', '2023-01-02', '2023-01-03', '2023-01-04'],
    'variable1': [10, 15, 7, 12],
    'variable2': [5, 8, 6, 11]
}

# 将数据转换为pandas DataFrame
df = pd.DataFrame(data)
df['timestamp'] = pd.to_datetime(df['timestamp'])

# 绘制线图
plt.figure(figsize=(10, 5))
plt.plot(df['timestamp'], df['variable1'], label='Variable 1')
plt.plot(df['timestamp'], df['variable2'], label='Variable 2')
plt.xlabel('Timestamp')
plt.ylabel('Value')
plt.title('Variable Comparison Over Time')
plt.legend()
plt.show()

library(ggplot2)

# 假设我们有两个时间戳和对应的变量值
data <- data.frame(
  timestamp = as.Date(c('2023-01-01', '2023-01-02', '2023-01-03', '2023-01-04')),
  variable1 = c(10, 15, 7, 12),
  variable2 = c(5, 8, 6, 11)
)

# 绘制线图
ggplot(data, aes(x = timestamp)) +
  geom_line(aes(y = variable1, color = 'Variable 1')) +
  geom_line(aes(y = variable2, color = 'Variable 2')) +
  labs(x = 'Timestamp', y = 'Value', title = 'Variable Comparison Over Time') +
  scale_color_manual(values = c('Variable 1' = 'blue', 'Variable 2' = 'red')) +
