Comment (by ncohen):
> I agree it's not perfect, as you may at first glance miss the
information that the value can be something else than a boolean. But I did
not find a better formulation without being heavy in the formaluation.
Better suggestions welcome. Maybe something like:
> {{{
> - ``color_by_label`` - a boolean, dictionary or function
(default: False)
> whether to color each edge with a different color according
> to its label; the value can be a function or
> dictionary mapping labels to colors; this option is
> incompatible with ``edge_color`` and ``edge_colors``.
> }}}
Well, saying that this variable is a boolean when it is not is clearly not
an option. What you just wrote looks nice !
> This is exactly what this is doing currently, isn't it?
Oh. Cool. I looked at the patch and did not see anything related with
rainbow, nor any loop, so I assumed it did not do it, but now I realise
that it was the former behaviour `:-)`
