matplotlib에서 축 눈금 레이블에 경로 효과를 추가하는 방법은 무엇입니까?

에 인수 path_effects=[pe.withStroke(linewidth=1, foreground="b")]를 전달할 수 있습니다 cb.ax.set_yticklabels. 예를 들어:

import numpy as np
from numpy.random import randn

import matplotlib.pyplot as plt
from matplotlib import patheffects as pe
from matplotlib import cm


# Fixing random state for reproducibility
np.random.seed(42)
# Make plot with vertical (default) colorbar

fig, ax = plt.subplots()

data = np.clip(randn(250, 250), -1, 1)

cax = ax.imshow(data, cmap=cm.coolwarm)
ax.set_title('Gaussian noise with vertical colorbar')

# Add colorbar, make sure to specify tick locations to match desired ticklabels
cb = fig.colorbar(cax, ticks=[-1, 0, 1])
cb.ax.set_yticklabels(['< -1', '0', '> 1', ], fontsize=18, path_effects=[pe.withStroke(linewidth=1, foreground="b")])  # vertically oriented colorbar

plt.show()
