从初级到高级，图解Matplotlib绘图的方法

import matplotlib.pyplot as plt

# 数据
months = ['Jan', 'Feb', 'Mar', 'Apr', 'May', 'Jun', 'Jul', 'Aug', 'Sep', 'Oct', 'Nov', 'Dec']
sales = [100, 120, 150, 130, 140, 160, 180, 170, 190, 200, 210, 220]

# 创建图表和画布
plt.figure(figsize=(8, 6))

# 绘制折线图
plt.plot(months, sales, marker='o', linestyle='-', color='blue')

# 设置标题和标签
plt.title('Sales Trend')
plt.xlabel('Months')
plt.ylabel('Sales')

# 显示图表
plt.show()

import matplotlib.pyplot as plt

# 数据
temperature = [15, 19, 22, 18, 25, 28, 30, 29, 24, 20]
rainfall = [20, 40, 30, 10, 55, 60, 70, 50, 45, 35]

# 创建图表和画布
plt.figure(figsize=(8, 6))

# 绘制散点图
plt.scatter(temperature, rainfall, color='red')

# 设置标题和标签
plt.title('Temperature vs Rainfall')
plt.xlabel('Temperature (°C)')
plt.ylabel('Rainfall (mm)')

# 显示图表
plt.show()

import matplotlib.pyplot as plt

# 数据
regions = ['North', 'South', 'East', 'West']
sales = [100, 120, 150, 130]

# 创建图表和画布
plt.figure(figsize=(8, 6))

# 绘制条形图
plt.bar(regions, sales, color='blue')

# 设置标题和标签
plt.title('Sales by Region')
plt.xlabel('Region')
plt.ylabel('Sales')

# 显示图表
plt.show()

import matplotlib.pyplot as plt

# 数据
products = ['A', 'B', 'C', 'D']
sales = [30, 20, 25, 15]

# 创建图表和画布
plt.figure(figsize=(8, 6))

# 绘制饼图
plt.pie(sales, labels=products, autopct='%.1f%%')

# 设置标题
plt.title('Sales by Product')

# 显示图表
plt.show()

import numpy as np
import matplotlib.pyplot as plt
from mpl_toolkits.mplot3d import Axes3D

# 数据
x = np.linspace(-5, 5, 100)
y = np.linspace(-5, 5, 100)
X, Y = np.meshgrid(x, y)
Z = np.sin(np.sqrt(X**2 + Y**2))

# 创建图表和画布
fig = plt.figure(figsize=(8, 6))
ax = fig.add_subplot(111, projection='3d')

# 绘制3D图
ax.plot_surface(X, Y, Z, cmap='viridis')

# 设置标题和标签
ax.set_title('3D Surface Plot')
ax.set_xlabel('X')
ax.set_ylabel('Y')
ax.set_zlabel('Z')

# 显示图表
plt.show()
