Pie 绘制饼图演示

使用 pie(). 制作饼图。

此示例演示了一些饼图功能，如标签、可变大小、自动标记百分比、偏移切片和添加阴影。

  1. import matplotlib.pyplot as plt
  3. # Some data
  4. labels = 'Frogs', 'Hogs', 'Dogs', 'Logs'
  5. fracs = [15, 30, 45, 10]
  7. # Make figure and axes
  8. fig, axs = plt.subplots(2, 2)
  10. # A standard pie plot
  11. axs[0, 0].pie(fracs, labels=labels, autopct='%1.1f%%', shadow=True)
  13. # Shift the second slice using explode
  14. axs[0, 1].pie(fracs, labels=labels, autopct='%.0f%%', shadow=True,
  15.               explode=(0, 0.1, 0, 0))
  17. # Adapt radius and text size for a smaller pie
  18. patches, texts, autotexts = axs[1, 0].pie(fracs, labels=labels,
  19.                                           autopct='%.0f%%',
  20.                                           textprops={'size': 'smaller'},
  21.                                           shadow=True, radius=0.5)
  22. # Make percent texts even smaller
  23. plt.setp(autotexts, size='x-small')
  24. autotexts[0].set_color('white')
  26. # Use a smaller explode and turn of the shadow for better visibility
  27. patches, texts, autotexts = axs[1, 1].pie(fracs, labels=labels,
  28.                                           autopct='%.0f%%',
  29.                                           textprops={'size': 'smaller'},
  30.                                           shadow=False, radius=0.5,
  31.                                           explode=(0, 0.05, 0, 0))
  32. plt.setp(autotexts, size='x-small')
  33. autotexts[0].set_color('white')
  35. plt.show()
