Re: [Matplotlib-users] Keep list of figures or plots and flip through list using UI

[Thomas C. <tca...@gm...>]

Please ping the mailing list again (I cc'd the list on this).

See
https://github.com/tacaswell/leidenfrost/blob/master/leidenfrost/gui/reader_gui.py#L636
(sorry for the code quality, this is a bespoked gui I wrote as part of my
PhD work, you might be the second person to ever read this code) for a Qt
object that wraps up a `Figure` in a nice-embedded way.  Using this
directly you can keep a list of these objects around and show/hide them
using standard Qt methods.  Modifying this a bit you could make this class
based on a standard Qt widget, embed them all in a main window/what have
you and then again use standard Qt methods to show/hide individual plots as
you wish.
