I finally managed to get through, but that cost me half a Saturday :(

Honestly, it is not a MoI discussion, but rather more an Illustrator one. I HATE Illustrator ! But I have to admit that eventually you do get professional-level art out of it, but why does it have to be that painful ?

Now, I just have to tackle the other chart, and maybe one or two others so that they all have the same look and feel.
