折线图

import numpy as np
from matplotlib import pyplot as plt
plt.rcParams['font.sans-serif'] = ['SimHei']  # 用来正常显示中文标签 plt.reParams是一个配置表
plt.rcParams['axes.unicode_minus'] = False  # 用来正常显示负号
plt.figure(figsize=(7, 5))
x = np.linspace(0, 2 * np.pi, 50)
y = np.sin(x)
plt.xlabel(u'自变量')
plt.ylabel(u'因变量')
plt.title(u'正弦曲线')
plt.plot(x, y, 'ro--') #红色圆圈加虚线
plt.show()

 饼图

from matplotlib import pyplot as plt

#画出饼图的关键就是定义标签和每一块的颜色
labels = ['Frogs', 'Hogs', 'Dogs', 'Logs']
sizes = [15, 30, 45, 10]
colors = ['yellowgreen', 'gold', 'lightskyblue', 'lightcoral']
explode = (0, 0.1, 0, 0) #突出显示

plt.pie(sizes, explode=explode, labels=labels, colors=colors, autopct='%1.1f%%', shadow=True, startangle=90)
plt.axis('equal')  #避免比例压缩为椭圆
plt.show()
