[Matplotlib-users] Subplot x-axis shared with other subplots y-axis

Hey Tom,

Thanks for that response, it was just what I needed! I had a fun infinite loop where the x-axis was updating the y-axis which was updating the x-axis which... =P But it was easy enough to sort out. =)

I have a working orthogonal slice viewer here:

The problem I have now is that, if I set a mouse-click callback (this line and this line), and then I select any other tool from the toolbar, I get this super-obnoxious flickering, recorded here (macOS 10.12, Tk backend):

To reproduce:

- Download slice_view.py and put it in your PYTHONPATH or current working directory
- Download this example dataset:
- Run this code:

import matplotlib

from skimage import io
import slice_view as sv

filename = '/path/to/E_z2_512_1um_CONTROL.tif'
image = io.imread(filename) / 4096

v = sv.SliceViewer(image, spacing=[5, 1, 1])

1) Any ideas about how to fix the flickering?
2) Is there a cross-backend way to add buttons to the toolbar? All the examples I've found online were backend-specific. (This way I could at least disable the callback at will.)
