Dear Peter,


thank you for your answer.

So how can I find out what the dimension of the path of a function is?
Not scaling it, it also looked pretty small, so I am guessing (1pt,1pt).

but if you use numbers with a unit than it should not be multiplied but
expanded to that value, should not it? Otherwise I am unsure how
multiplication works with a unit.

Thank you for your answer. As written above it is still not entirely
clear to me. I hope you can remedy my last confusion.


Thanks a lot,

Paul
