Hello Benjamin,
last weekend (after more than a year... :-[ ) I found some spare time to
refactor a bit the solution I implemented to solve the axis synchronisation.
I have answered my own question on stackoverflow
(http://stackoverflow.com/questions/28239054/update-the-x-axis-of-a-matplotlib-subplot-according-to-the-y-axis-of-a-different/37265661#37265661)
and I have shared on github
(https://github.com/apbard/OrthogonalProjection) a simple class that
allows to easily make orthogonal projections plots with full axis
syncronisation and support for different basic plot types.
Thanks again for the hint and sorry for the delay...

thanks for your answer.
I have played a bit with the callbacks and seems very promising.
i'll work on it in the weekend and drop an email as soon as I have
tested it properly :)
thanks again

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.

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

Sounds to me like you want to use glue:

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
Alessandro
