Elegantly changing the color of a plot frame in matplotlib

Question

This is a kind of follow-up question to this post, where the coloring of axes, ticks and labels was discussed. I hope it is alright to open a new, extended question for this

Answer 1

Assuming you're using a reasonably up-to-date version of matplotlib (>= 1.0), perhaps try something like this:

import matplotlib.pyplot as plt

# Make the plot...
fig, axes = plt.subplots(nrows=2)
axes[0].plot(range(10), 'r-')
axes[1].plot(range(10), 'bo-')

# Set the borders to a given color...
for ax in axes:
    ax.tick_params(color='green', labelcolor='green')
    for spine in ax.spines.values():
        spine.set_edgecolor('green')

plt.show()
