Text 保存期间隐藏Matplotlib文本

我有一个“暂停”Matplotlib文本，告诉用户图形已暂停。这非常有效，但我不希望在打印或保存时显示“暂停”一词

figPausedText = fig.text(0.5, 0.5,'Paused', horizontalalignment='center',
    verticalalignment='center',
    transform=ax.transAxes,
    alpha = 0.25,
    size='x-large')

保存/打印时隐藏暂停文本的最佳方法是什么？如果我可以绑定到所有保存和打印命令，我很乐意设置文本（“”）。我特别想确保当用户单击NavigationToolbar2TkAgg工具栏时，它能正常工作。

类似于以下内容：

figPausedText = fig.text(...)
def my_save(fig, * args, **kwargs):
     figPausedText.set_visible(False)
     fig.savefig(*args, **kwargs)
     figPausedText.set_visible(True)

如果你想变得更聪明，你可以用猴子修补你的

对象：

import types

figPausedText = fig.text(...)
# make sure we have a copy of the origanal savefig
old_save = matplotlib.figure.Figure.savefig
# our new function which well hide and then re-show your text
def my_save(fig, *args, **kwargs):
     figPausedText.set_visible(False)
     ret = old_save(fig, *args, **kwargs)
     figPausedText.set_visible(True)
     return ret
# monkey patch just this instantiation  
fig.savefig = types.MethodType(my_save, fig)

或者，如果需要通过工具栏执行此操作

import types

figPausedText = fig.text(...)
# make sure we have a copy of the origanal print_figure
old_print = fig.canvas.print_figure # this is a bound function
# if we want to do this right it is backend dependent
# our new function which well hide and then re-show your text
def my_save(canvas, *args, **kwargs):
     figPausedText.set_visible(False)
     ret = old_print(*args, **kwargs) # we saved the bound function, so don't need canvas
     figPausedText.set_visible(True)
     return ret
# monkey patch just this instantiation  
fig.canvas.print_figure = types.MethodType(my_save, fig.canvas)

大概是这样的：

figPausedText = fig.text(...)
def my_save(fig, * args, **kwargs):
     figPausedText.set_visible(False)
     fig.savefig(*args, **kwargs)
     figPausedText.set_visible(True)

这看起来不错，但不幸的是，单击NavigationToolbar2TkAgg保存按钮时未调用my_保存。这如何与NavigationToolbar2TkAgg一起工作？我尝试了当时的monkey补丁

画布上的变体。打印\u figure

而不是通过gui工具栏编辑您的问题，以表明您希望此操作正常。这看起来不错，但不幸的是，单击NavigationToolbar2TkAgg save按钮时未调用my\u save。这如何与NavigationToolbar2TkAgg一起工作？我尝试了当时的monkey patch
