Question

我正在尝试在matplotlib中设置轴刻度的默认字体。目前我设置了字体路径：

path = 'palatino-regular.ttf'
prop = font_manager.FontProperties(fname=path)

对于每个图，我必须使用命令更改刻度字体：

for label in ax.get_xticklabels():
    label.set_fontproperties(prop)
for label in ax.get_yticklabels():
    label.set_fontproperties(prop)

有没有办法全局设置刻度字体，这样我就不必在本地为每个我绘制的图形提供这些命令。

可重现的代码

import numpy as np
import matplotlib.pyplot as plt
import itertools
import matplotlib.font_manager as font_manager

path = 'palatino-regular.ttf'
prop = font_manager.FontProperties(fname=path)

m = 5
n = 5
x = np.zeros(shape=(m, n))
plt.figure(figsize=(5.15, 5.15))
plt.clf()
plt.subplot(111)
marker = itertools.cycle(('o', 'v', '^', '<', '>', 's', '8', 'p'))
ax = plt.gca()
for i in range(1, n):
    x = np.dot(i, [1, 1.1, 1.2, 1.3])
    y = x ** 2
    color = next(ax._get_lines.color_cycle)
    plt.plot(x, y, linestyle='', markeredgecolor='none', marker=marker.next(), color=color, label = str(i))
    plt.plot(x, y, linestyle='-', color = color)
plt.ylabel(r'y', labelpad=6)
plt.xlabel(r'x', labelpad=6)
for label in ax.get_xticklabels():
    label.set_fontproperties(prop)
for label in ax.get_yticklabels():
    label.set_fontproperties(prop)
plt.show()

我也尝试在matplotlibrc中设置字体，但是我收到以下错误：

/opt/share/python/v2.7.9.app/lib/python2.7/site-packages/matplotlib/font_manager.py:1236: UserWarning: findfont: Font family ['palatino-regular'] not found. Falling back to Bitstream Vera Sans
  (prop.get_family(), self.defaultFamily[fontext]))

如何在matplotlib中设置刻度的默认字体？
