This is a brilliant contribution. Thank you!
I have found a bug with reproducing textbox annotations. The left-hand edge is not reproduced. A simple example is:
annotation('textbox',[0.2 0.3 0.6 0.4],'String','test')
I have an issue getting plot2svg working on matlab 2014b, whereas it worked perfectly before.
Initially I had the some problem as Mirko, but I was able to fix it using the comments below. I now get the following errors:
Warning: Unhandled child type: contour
Warning: Unhandled main figure child type: colorbar
The code produces an svg file but the axes are empty and there is no colorbar.
