Re: [matplotlib-devel] update x axis of a subplot according to the y axis of another one in python/matplotlib

2016-06-10 Thread Alessandro Pietro Bardelli 

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

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

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?
