import matplotlib.pyplot as plt

# 数据
x = [1, 2, 3, 4, 5]
y = [2, 3, 5, 7, 11]

# 绘图
plt.plot(x, y)

# 添加标题和标签
plt.title('Simple Line Plot')
plt.xlabel('X-axis')
plt.ylabel('Y-axis')

# 显示图形
plt.show()

import matplotlib.pyplot as plt
import numpy as np

# 数据
x = np.linspace(0, 10, 100)
y1 = np.sin(x)
y2 = np.cos(x)

# 创建一个包含两个子图的图形
fig, (ax1, ax2) = plt.subplots(2, 1)

# 在第一个子图中绘制正弦函数
ax1.plot(x, y1, 'r-')
ax1.set_title('Sine Function')
ax1.set_xlabel('X-axis')
ax1.set_ylabel('Y-axis')

# 在第二个子图中绘制余弦函数
ax2.plot(x, y2, 'g--')
ax2.set_title('Cosine Function')
ax2.set_xlabel('X-axis')
ax2.set_ylabel('Y-axis')

# 设置图形的整体标题
plt.suptitle('Sine and Cosine Functions')

# 自定义图形的风格
plt.style.use('ggplot')

# 调整子图的间距
plt.tight_layout()

# 显示图形
plt.show()
