I just wanted to know if it is possible to write things into diagrams. I'm writing a scientific paper in German. So I need to edit a diagram by removing all English descriptions and writing them in German again.
To make the whole thing easier, I posted a graphic. 
As you see everything is in English. So I need to edit everything to become in German. And to get a good quality I think It's better to even write the labelling and the numbers on the axes myself.
