Spines图

这个演示比较：

  • 正常轴，四边都有spine;
  • 仅在左侧和底部有spine的轴;
  • 使用自定义边界限制spine范围的轴。

Spines图示例

  1. import numpy as np
  2. import matplotlib.pyplot as plt
  5. x = np.linspace(0, 2 * np.pi, 100)
  6. y = 2 * np.sin(x)
  8. fig, (ax0, ax1, ax2) = plt.subplots(nrows=3)
  10. ax0.plot(x, y)
  11. ax0.set_title('normal spines')
  13. ax1.plot(x, y)
  14. ax1.set_title('bottom-left spines')
  16. # Hide the right and top spines
  17. ax1.spines['right'].set_visible(False)
  18. ax1.spines['top'].set_visible(False)
  19. # Only show ticks on the left and bottom spines
  20. ax1.yaxis.set_ticks_position('left')
  21. ax1.xaxis.set_ticks_position('bottom')
  23. ax2.plot(x, y)
  25. # Only draw spine between the y-ticks
  26. ax2.spines['left'].set_bounds(-1, 1)
  27. # Hide the right and top spines
  28. ax2.spines['right'].set_visible(False)
  29. ax2.spines['top'].set_visible(False)
  30. # Only show ticks on the left and bottom spines
  31. ax2.yaxis.set_ticks_position('left')
  32. ax2.xaxis.set_ticks_position('bottom')
  34. # Tweak spacing between subplots to prevent labels from overlapping
  35. plt.subplots_adjust(hspace=0.5)
  36. plt.show()
