>>> fig = dt.plot(kind='bar', use_index=True)
>>> fig
<matplotlib.axes.AxesSubplot object at 0x0B387150>但我希望将<matplotlib.figure.Figure object>传递给其他函数,就像下面的对象类型一样:
>>> plt.figure()
<matplotlib.figure.Figure object at 0x123A6910>那么,如何将<matplotlib.axes.AxesSubplot object>转换为<matplotlib.figure.Figure object>或直接从Pandas plot返回"Figure object“呢?

您可以从axes对象中获取该图形:
ax.get_figure()完整示例:
df = pd.DataFrame({'a': range(10)})
ax = df.plot.barh()
ax.get_figure()https://stackoverflow.com/questions/14936646
