Re: [Matplotlib-users] creating an object oriented matplotlib figure

[Kelson Z. <kb...@co...>]

So I looked into it and the reason calling the show method for a 
Figure/FigureManager causes the figure to be visible only for an instant 
is that, at least in the case for tkagg, there is no call to a function 
that blocks until the figure window is closed and as a result the figure 
is displayed then the call to show ends, the figure closes, and the 
program moves on.  This is in contrast to the behavior of the callable 
object invoked by pyplot.show() which calls a mainloop method to block.  
Since I am not super familiar with the internals of Matplotlib I am not 
sure the best way to fix this, but one option, in the case of tkagg, is 
to add a call to tk.mainloop() to the end of FigureManagerTkAgg.show() 
as is done in tkagg's Show object.

Just my 2 cents
