<div><br></div>
<div>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. =)</div>

<div>I have a working orthogonal slice viewer here:</div>
<div><a href="https://github.com/jni/mpl-volume-viewer/" target="_blank">https://github.com/jni/mpl-<wbr>volume-viewer/</a><br></div>
<div><br></div>
<div>The problem I have now is that, if I set a mouse-click callback (<a href="https://github.com/jni/mpl-volume-viewer/blob/6d863d2a28ced54576c6f4f8905d58e229f02042/slice_view.py#L71" target="_blank">this line</a> and <a href="https://github.com/jni/mpl-volume-viewer/blob/6d863d2a28ced54576c6f4f8905d58e229f02042/slice_view.py#L101" target="_blank">this line</a>), and then I select any other tool from the toolbar, I get this super-obnoxious flickering, recorded here (macOS 10.12, Tk backend):</div>

<div><br></div>
<div>To reproduce:</div>
<div><br></div>
<div>- Download slice_view.py and put it in your PYTHONPATH or current working directory</div>
<div>- Download this example dataset: </div>
<div><a href="https://www.dropbox.com/s/dj3oarx7bqx4us2/E_z2_512_1um_CONTROL.tif?dl=1" target="_blank">https://www.dropbox.com/s/<wbr>dj3oarx7bqx4us2/E_z2_512_1um_<wbr>CONTROL.tif?dl=1</a><br></div>
<div>- Run this code:</div>
<div><br></div>
<div>
<div><i>import matplotlib</i></div>
<div><i>matplotlib.use('TkAgg')</i></div>
<div><i><br></i></div>
<div><i>from skimage import io</i></div>
<div><i>import slice_view as sv</i></div>
<div><i><br></i></div>
<div><i>filename = '/path/to/E_z2_512_1um_<wbr>CONTROL.tif'</i></div>
<div><i>image = io.imread(filename) / 4096</i></div>
<div><i><br></i></div>
<div><i>v = sv.SliceViewer(image, spacing=[5, 1, 1])</i></div>
<div><i>matplotlib.pyplot.show(block=<wbr>True)</i></div>
</div>
<div><br></div>
<div>Questions:</div>
<div>1) Any ideas about how to fix the flickering?</div>
<div>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.)</div>

<div>This is probably the best route to go down as you can do other interesting things as the event goes by (like triggering computation, updating a openGL view window, etc) as well as updating the Matplotlib limits.</div>

<div name="messageBodySection" style="font-size:14px;font-family:-apple-system,BlinkMacSystemFont,sans-serif">Hello,
<div><br></div>
<div>I’m trying to build an orthogonal-views volume viewer in Matplotlib like this one:</div>
<div><a href="https://imagej.nih.gov/ij/docs/guide/images/OrthogonalViews.png" target="_blank">https://imagej.nih.gov/ij/<wbr>docs/guide/images/<wbr>OrthogonalViews.png</a><br></div>
<div><br></div>
<div>For this to work, I need to share the y-axis of the YZ (right) view/subplot with the x-axis of the XZ (bottom) view/subplot. Is this possible?</div>
<div><br></div>
<div>Juan.</div>
