How to return a matplotlib.figure.Figure object from Pandas plot function?

And use pandas function plotto create a barplot object
并使用pandas函数plot创建一个barplot对象
>>> fig = dt.plot(kind='bar', use_index=True)
>>> fig
<matplotlib.axes.AxesSubplot object at 0x0B387150>
But I want a <matplotlib.figure.Figure object>intsead to pass to other function, just like the object type below:
但我想要一个<matplotlib.figure.Figure object>intsad 传递给其他函数，就像下面的对象类型：
>>> plt.figure()
<matplotlib.figure.Figure object at 0x123A6910>
So how can I transform <matplotlib.axes.AxesSubplot object>to <matplotlib.figure.Figure object>or directly return "Figure object" from Pandas plot ?
那么如何从 Pandas plot转换<matplotlib.axes.AxesSubplot object>为<matplotlib.figure.Figure object>或直接返回“Figure object”？

You can get the figure from the axes object:
您可以从轴对象中获取图形：
ax.get_figure()
