Add rejected edges back to the output with undefined value

[Domajno]

Hi

I had this example where I had data set of 500 edges containing also weights and additional metadata about them. As the output of d3.ForceBundle I got an array of 478 elements but I didn't know which edges were deleted so I couldn't associate this metadata with the new edges anymore.

What I suggest is to always return an array of the same size as the input edges array but some elements may be undefined - those which were rejected. I guess there are many ways to approach this problem and this is one possible solution.

Cheers

Hi, Dominik,

I think the deleted (or filtered) edges may be absolute horizontal or vertical edges, may be you can have a try of this fork version here:
https://github.com/godoorsun/d3.ForceBundle
which is discussed in my yesterday's pull request.

As Guodao pointed out they might have been filtered because of a bad check. Vertical and horizontal edges mostly likely were removed, otherwise the filtering function should only remove edges with no length. I think you can pre-check the data for that, it's not necessarily hard, but if you update your code I might merge it.
