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...
