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

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

Sorry this didn't get a response for so long.

The core of the embedding in Qt is at QWidget which contains the canvas.
Anything you want to do with a QWidget you can do with the canvas.
Independently
you need to maintain the mpl level plotting objects (the Figure, Axes, and
Artist objects) (well, you don't _need_ to, you can get to them through the
canvas object, but to keep your self sane I highly recommend keeping track
of the mpl objects your self, this linkage is there so that GUI generated
draw commands can trigger a re-rendering of the figure).

I would just have a widget for each of the plots you want to have and then
cycle which one is visible in the main window, that is probably a lot
easier than trying to attach and detach canvases from Figures.

I would also take a look at glue
http://www.glueviz.org/en/stable/installation.html who may have solved many
of these problems for you.
