Hi Calixte

Thank you for this infromation, and "bon courage" with that. I know by 
experience that printing 3d structures is quite difficult.

I look forward to use the 2D solution, which is by far the most useful 
feature for me (In my field, you typically make plots of 2 to 6 time 
series, and you want them to be clear when printed in 2d, and also 
beautiful when viewed in color in the pdf article.)

Kind regards
