ggplot样式表

此示例演示了“ggplot”样式，该样式调整样式以模拟ggplot（R的流行绘图包）。

这些设置被无耻地从[1]窃取(经允许)。

ggplot样式表示例

  1. import numpy as np
  2. import matplotlib.pyplot as plt
  4. plt.style.use('ggplot')
  6. # Fixing random state for reproducibility
  7. np.random.seed(19680801)
  9. fig, axes = plt.subplots(ncols=2, nrows=2)
  10. ax1, ax2, ax3, ax4 = axes.ravel()
  12. # scatter plot (Note: `plt.scatter` doesn't use default colors)
  13. x, y = np.random.normal(size=(2, 200))
  14. ax1.plot(x, y, 'o')
  16. # sinusoidal lines with colors from default color cycle
  17. L = 2*np.pi
  18. x = np.linspace(0, L)
  19. ncolors = len(plt.rcParams['axes.prop_cycle'])
  20. shift = np.linspace(0, L, ncolors, endpoint=False)
  21. for s in shift:
  22.     ax2.plot(x, np.sin(x + s), '-')
  23. ax2.margins(0)
  25. # bar graphs
  26. x = np.arange(5)
  27. y1, y2 = np.random.randint(1, 25, size=(2, 5))
  28. width = 0.25
  29. ax3.bar(x, y1, width)
  30. ax3.bar(x + width, y2, width,
  31.         color=list(plt.rcParams['axes.prop_cycle'])[2]['color'])
  32. ax3.set_xticks(x + width)
  33. ax3.set_xticklabels(['a', 'b', 'c', 'd', 'e'])
  35. # circles with colors from default color cycle
  36. for i, color in enumerate(plt.rcParams['axes.prop_cycle']):
  37.     xy = np.random.normal(size=2)
  38.     ax4.add_patch(plt.Circle(xy, radius=0.3, color=color['color']))
  39. ax4.axis('equal')
  40. ax4.margins(0)
  42. plt.show()
