update x axis of a subplot according to the y axis of another one in python/matplotlib

Development matplotlib-devel
#1

I would like to plot an orthogonal projection (like this one http://i.stack.imgur.com/DnNds.jpg )
using matplotlib possibly including also the 3D subplot. All the
pictures should share common axes.

fig = plt.figure()
ax = fig.add_subplot(221, title="XZ")
bx = fig.add_subplot(222, title="YZ", sharey=ax)
cx = fig.add_subplot(223, title="XY", sharex=ax, sharey=[something like bx.Xaxis])
dx = fig.add_subplot(224, title="XYZ", projection="3d", sharex=ax, sharey=bx, sharez=[something like bx.Yaxis]

    The problem is that I have to "link" on X axis of a plot with

the Y one of another and
Is there a way to accomplish this?

Thanks

Sounds to me like you want to use glue: http://www.glueviz.org/en/stable/

Thanks for the answer.
Glue seems a quite cool project but it is also a bit overkill for
this specific task, isn’t it?
Basically I just would like tell sharex to point the Yaxis of the
axes object.
Isn’t there a way to do this within matplotlib?
thanks

Sharing the same axis across subplots is implemented via matplotlib’s interactive framework, and is available by default. Glue is built on top of matplotlib, extending its interactive framework with many additional tools. Yes, it might be overkill for this singular task, but implementing orthogonal axis sharing isn’t trivial, either, so suggesting a pre-packaged solution is merely pragmatic.

Essentially, one would have to register callbacks for changes in each of the parent subplot’s axis. This, in of itself, isn’t really all that difficult once one learns the event framework. I think what might be very tricky is doing it for the 3d axes. As the de facto maintainer of mplot3d, I have never really tested axis sharing for mplot3d. I suspect that it would work exactly as you’d expect for the x and y axes, but the z axis may prove to be quirky. I don’t know, I haven’t ever tried it out. In general, the z-axis implementation is a bit of a kludge, so things tend to be different for it…

Here is an example of how to register callbacks to changes in a particular axis. Hopefully, it can give you a nice leg up on the problem. Let me know if you have problems with the z-axis, I might be able to help sort it out. If you can get this to work, I would certainly love to include it in the gallery.
