在不更改 rcParams 全局字典的情况下设置 axes.linewidth [英] Setting axes.linewidth without changing the rcParams global dict

问题描述

因此，似乎不能执行以下操作(它会引发错误，因为 axes 没有 set_linewidth 方法):

axes_style = {'linewidth':5}axis_rect = [0.1, 0.1, 0.9, 0.9]轴(axes_rect，**axes_style)

并且必须使用以下旧技巧:

rcParams['axes.linewidth'] = 5 # 全局设置值... # 一些代码rcdefaults() # 恢复 [全局] 默认值

是否有一种简单/干净的方法(可能可以单独设置 x- 和 y- 轴参数等)?

如果不是，为什么?

解决方案

    • http://matplotlib.org/examples/pylab_examples/multiple_yaxis_with_spines.html

  So, it seems one cannot do the following (it raises an error, since axes does not have a set_linewidth method):

  axes_style = {'linewidth':5}
  axes_rect = [0.1, 0.1, 0.9, 0.9]
  
  axes(axes_rect, **axes_style)
  

  and has to use the following old trick instead:

  rcParams['axes.linewidth'] = 5 # set the value globally
  
  ... # some code
  
  rcdefaults() # restore [global] defaults
  

  Is there an easy / clean way (may be one can set x- and y- axes parameters individually, etc)?

  If no, why?

  解决方案

  • This answer does not work, as it is explained in the comments. I suggest using spines.
  • As mentioned in a comment by Czechnology, consider changing the ticks too.

  import matplotlib.pyplot as plt
  
  fig, (ax1, ax2) = plt.subplots(1, 2, figsize=(10, 4))
  
  ax1.set_title('Normal spine and ticks')
  ax2.set_title('Adjusted spine and ticks')
  
  # change each spine separately:
  # ax.spines['right'].set_linewidth(0.5)
  
  # change all spines
  for axis in ['top','bottom','left','right']:
      ax2.spines[axis].set_linewidth(4)
  
  # increase tick width
  ax2.tick_params(width=4)
  
  plt.show()
