Matplotlib FigureCanvas widget

See original GitHub issue

Hi, thanks a lot for magicgui,

Usecase

I’m trying to use it to create a simple waveform generator: choose a function (e.g scipy.signal.chirp) have the corresponding magic widget, and (among maybe other things), plot the result within the widget

Attempt

In order to do that, I tried to wrap the FigureCanvas class from matplotlib.backends.backend_qt5agg, which is a QWidget instance, in a Container, which, as discussed in #314 does not seem to be feasible.

Plea

Is there an easy way to do that? Could a FigureCanvas widget be implemented in magicgui?

As matplotlib is the most used plotting backend, and magicgui already depends on it, it seems to me that this would make sense for scientific applications.

Thanks for any hint!

Best,

Guillaume

For completeness, a POC implementation of the waveform generator is here:

looks good! I’d probably use cont.native.layout() instead of cont.native.children()[0] … just in case it’s not the first child
