matplotlib 绘制正余弦曲线图

1、普通风格

代码

import numpy as npimport matplotlib.pyplot as plt

x = np.linspace(0, 2*np.pi, 50)y1 = np.sin(x)y2 = np.cos(x)xticks=[0, np.pi/2, np.pi, 3*np.pi/2, 2*np.pi]

plt.figure(‘赏尔‘)

plt.plot(x, y1, c=‘g‘, marker=‘.‘, ls=‘--‘, label=‘sin(x)‘)plt.plot(x, y2, ‘y.--‘, label=‘cos(x)‘)plt.xlabel(‘x‘)plt.ylabel(‘sin/cos‘)plt.xticks(xticks,)plt.legend()

plt.show()

图形

2、特别风格

代码

import numpy as npimport matplotlib.pyplot as plt

x = np.linspace(0, 2*np.pi, 50)y1 = np.sin(x)y2 = np.cos(x)xticks=[0, np.pi/2, np.pi, 3*np.pi/2, 2*np.pi]

plt.figure(‘赏尔‘, facecolor=‘azure‘)

plt.plot(x, y1, c=‘g‘, marker=‘p‘, ls=‘--‘,          mec=‘r‘, mfc=‘g‘, ms=7, mew=0.71,         label=‘sin(x)‘)plt.plot(x, y2, ‘yp--‘, mec=‘r‘, mfc=‘gold‘, ms=7, mew=0.72,         label=‘cos(x)‘)plt.xlabel(‘x‘)plt.ylabel(‘sin/cos‘)plt.xticks(xticks)plt.legend()

plt.show()

图形
