[Graph] Number fields issue with minimum number 1

[philippkahr]

Hi,

I do not feel like the "1 is the minimum number in this box" is the best solution there is.

Let's say I want to change the value 1 to value 20.

Currently, I have to perform the following strokes:
20◀️◀️⬅️
as I cannot remove the 1, I have to write 120 and then go the one and delete the one.

Ideally, I would be able to do something like this:
⬅️20

I am talking about those fields:

Maybe we can modify the evaluation of the number typed as soon as someone presses enter or the focuses shifts?
