如何使用python在一个条形图上绘制来自两个数据集的天气数据？

pip install matplotlib

import matplotlib.pyplot as plt
import numpy as np

# 创建数据
high_temperatures = [30, 32, 28, 29, 31]
low_temperatures = [20, 22, 18, 19, 21]
months = ['Jan', 'Feb', 'Mar', 'Apr', 'May']

# 设置条形图的位置和宽度
bar_positions = np.arange(len(months))
bar_width = 0.35

# 绘制条形图
plt.bar(bar_positions, high_temperatures, bar_width, label='High Temperatures')
plt.bar(bar_positions + bar_width, low_temperatures, bar_width, label='Low Temperatures')

# 添加标签和标题
plt.xlabel('Months')
plt.ylabel('Temperature (°C)')
plt.title('Weather Data')

# 添加刻度标签
plt.xticks(bar_positions + bar_width / 2, months)

# 添加图例
plt.legend()

# 显示图形
plt.show()
