Dear Kwant developers,

I'm playing with the current maps and there is something I don't understand. I attatch a current plot of a 2 terminal-device of some edge states in a particular model of graphene (the current is the sum of all wavefunctions from the incoming lead which is positioned at the left). I understand thus that the arrows point from left to right, it's the current direction. But then, in one edge I have a stronger color meaning there is more current there, but on the other hand, in the other edge the arrow is thicker, which I assume it also represents more current. Does the arrow thickness and color represent the same thing and therefore both edges have the same current or do they represent different things and so I'm missing something? Could you please clarify this for me?

In addition, when I plot the spin current projected on the Z axis (as in Kwant's documentation), I assume that the direction of the arrow is for example where the spin-up electrons move, while the spin-down electrons move to the other direction. Is this correct?
