How to make the edges fill gradient?

[Ademir Gabardo <ademir.gabbardo AT gmail.com>]

Dear friends from the list.

I have been trying all day long to make the color fill for the edges in gradient, I want them to fill gradient from source to target (Similar to Gephi).

Have tried many combinations with ui.color attribute, ui.style, ui.class.. Nothing make the edges gradient.

Anyone in the list ever succeed on this task?

Kind Regards,

Ademir
