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

If you're recursively creating (non-rectangular) axes using pyplot, you can change the linewidth parameter for each ax.

For instance:

import matplotlib.pyplot as plt

plt.figure(figsize = figsize)
fig, ax = plt.subplots(figsize = figsize)
for shape in sf.shapeRecords():
    x = [i[0] for i in shape.shape.points[:]]
    y = [i[1] for i in shape.shape.points[:]]
    ax.plot(x, y, 'k', linewidth=5)

For documentation, see MPL.axes documentation (Scroll down until "Other Parameters" -> **kwargs)

N.B. "If you make multiple lines with one plot command, the kwargs apply to all those lines."

Maybe this solution is related to a different question asked elsewhere, but I found this page looking for a solution to my own problem, so maybe it can help others looking for the same thing.
