Matplotlib:重新打开封闭的数字？

Question

是否有可能在matplotlib中重新打开一个封闭的数字(即用户X'd)？以下代码显示了天真的方法:

In [14]: fig = figure(10)

In [15]: close(fig)

In [16]: fig.show()

Exception in Tkinter callback
Traceback (most recent call last):

    tkagg.blit(self._tkphoto, self.renderer._renderer, colormode=2)

TclError: this isn't a Tk application

我正在尝试创建一个带有小部件的图形,因此可以使用一种解决方法(只需创建一个新图形),但我想知道该figure实例在关闭后是否完全没用.

是的，关闭图形会将其完全删除。
