Dataframe的plot方法如何定義字體

使用axis類來定義：

from matplotlib.figure import Figure
from matplotlib.text import Text

featp = df.plot(kind='barh', x='feature', y='fscore', legend=False, figsize=(6, 6))
fig_featp = featp.get_figure()
assert isinstance(fig_featp, Figure)
axs = fig_featp.get_axes()
for ax in axs:
    for tick in ax.get_yticklabels():
        tick.set(fontname=font_name, fontsize=12)

    for tick in ax.get_xticklabels():
        print(type(tick))
        assert isinstance(tick, Text)
        tick.set(fontname=font_name, fontsize=12)
        # tick.set_fontsize(12)
        tick.set_fontname(font_name)
plt.rcParams.update({'figure.autolayout': True})
plt.show()
plt.close()
