Setting `axes.linewidth` without changing the `rcParams` global dict

Question

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

axes_style = {\'lin         


        

Answer 1

The above answer does not work, as it is explained in the comments. I suggest to use spines.

import matplotlib.pyplot as plt

fig = plt.figure()
ax = fig.add_subplot(111)

# you can change each line separately, like:
#ax.spines['right'].set_linewidth(0.5)
# to change all, just write:

for axis in ['top','bottom','left','right']:
  ax.spines[axis].set_linewidth(0.5)

plt.show()
