Re: [Matplotlib-users] Preserving figure over closes and reopenings of the window

[Maciej K. <kur...@gm...>]

Ben,

The adjusting and aspect solution works just perfect, thanks for your 
fast answer. Although i still want to ask for another solution for 
reloading a plot, because i don't like the idea of serialization and 
writing to disk. From what i've found even if i have a variables 
handling figure and axis when i quit the window some part of it probably 
form the window framework are deleted anyway. In this case i think i can 
redraw all the artists on the newly created figure somehow but is there 
a relatively simple way to just set up new window and attach the old 
figure there?
