matplotlib-devel Mailing List for matplotlib

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...
Alessandro

I'm using v1.5.1 and I was reading the discussion on
https://github.com/matplotlib/matplotlib/pull/3652
and trying to reproduce the toolbar manipulation shown at
https://github.com/fariza/pycon2015/blob/master/ToolDemo.ipynb
I can't get it to work from either regular python or ipython
(console), at least not with my WXagg, GTKagg or GTKCairo backends.
In my matplotlibrc I have set toolbar to be toolmanager.
After successfully getting a figure window with fig, ax =
plt.subplots(), I find that fig.canvas.manager.toolbar is None and
there is no toolmanager attribute in the manager.
Did I miss something that has changed, because the pull seemed to
apply to 1.5.1?
Thanks,
Rob
