连接图样式

举例说明三种不同的连接样式。

  1. import numpy as np
  2. import matplotlib.pyplot as plt
  4. def plot_angle(ax, x, y, angle, style):
  5.     phi = np.radians(angle)
  6.     xx = [x + .5, x, x + .5*np.cos(phi)]
  7.     yy = [y, y, y + .5*np.sin(phi)]
  8.     ax.plot(xx, yy, lw=8, color='blue', solid_joinstyle=style)
  9.     ax.plot(xx[1:], yy[1:], lw=1, color='black')
  10.     ax.plot(xx[1::-1], yy[1::-1], lw=1, color='black')
  11.     ax.plot(xx[1:2], yy[1:2], 'o', color='red', markersize=3)
  12.     ax.text(x, y + .2, '%.0f degrees' % angle)
  14. fig, ax = plt.subplots()
  15. ax.set_title('Join style')
  17. for x, style in enumerate((('miter', 'round', 'bevel'))):
  18.     ax.text(x, 5, style)
  19.     for i in range(5):
  20.         plot_angle(ax, x, i, pow(2.0, 3 + i), style)
  22. ax.set_xlim(-.5, 2.75)
  23. ax.set_ylim(-.5, 5.5)
  24. plt.show()

连接图样式

  1. import matplotlib.pyplot as plt
  2. import numpy as np
  4. x = np.linspace(0, 2 * np.pi, 20)
  5. y = np.sin(x)
  6. yp = None
  7. xi = np.linspace(x[0], x[-1], 100)
  8. yi = np.interp(xi, x, y, yp)
  10. fig, ax = plt.subplots()
  11. ax.plot(x, y, 'o', xi, yi, '.')
  12. plt.show()
