Hi!
Are there any examples about the usage with glfw?
I'm trying to understand if I can use fastplotlib with https://github.com/pthom/imgui_bundle (that relies on glfw).

Thanks a lot!

   Hi! Thanks for your interest! I am also interested in integrating this with imgui, see this recent dicussion: pyimgui/pyimgui#336

   I just pushed a new release which contains a small fix to make the minimal install work: https://github.com/kushalkolar/fastplotlib#minimal-use-with-your-own-qt-or-glfw-applications

   You will need to pip install glfw in addition to that.

   For examples using glfw, use any of the desktop examples here:
   https://github.com/kushalkolar/fastplotlib/tree/master/examples/desktop

   Give the kwarg canvas="glfw" when constructing a Plot or GridPlot to force glfw. Don't forget to call fpl.run() at the end.

   For example with image_simple.py: https://github.com/kushalkolar/fastplotlib/blob/master/examples/desktop/image/image_simple.py

   from fastplotlib import Plot, run
   import imageio.v3 as iio
   
   # force glfw
   plot = Plot(canvas="glfw")
   
   data = iio.imread("imageio:camera.png")
   
   # plot the image data
   image_graphic = plot.add_image(data=data, name="iio camera")
   
   plot.show()
   
   plot.canvas.set_logical_size(800, 800)
   
   plot.auto_scale()
   
   # show and run
   plot.show()
   run()

   You can also use the example notebooks and pass canvas="glfw" to Plot or GridPlot and it will use the glfw canvas without blocking notebook executation.

   Hi @kushalkolar!
   Thanks a lot for your answer!
   Your example works fine!
   I'll let you know if I manage to make it work with imgui-bundle, which is a batteries-included version of pyimgui.

   Thank you!

   My guess is that imgui integration would probably be done with wgpu-py and pygfx, since fastplotlib is built on top of pygfx.

   See related discussion: pyimgui/pyimgui#336

   I don't have experience with imgui, very interested to see what you find out!

   @mbignotti wondering if you were able to try this out?

   Hey @kushalkolar,
   I'm really sorry, but I stopped working on the imgui project a few weeks after I opened this issue and I totally forgot to reply here. My apologies!
   Unfortunately I haven't had the chance to try it out. The original idea was trying to mimic what is being done in this fantastic series (at a much simpler level, of course), but with numpy, numba and imgui. Then I thought I could try use fastplotlib to display the image in real time.
   Unfortunately, other priorities had arrived in the mean time, and I abandoned the project. Sorry again.

   Thanks for the update! Creating viewports/subplots in a drag-drop-resize fashion would be really cool. I might just try and learn ImGUI soon and try to do it myself, but it has been years since I've touched C++ and my C++ abilities are very basic.

   I don't think that using C++ is necessary here. The python bindings provide the same functionalities. However, I don't know if fastplotlib can be used to display an image inside an imgui window.
