If I display link labels at the source extremity of links, they tend to collide with their source node at certain angles. See for example the screenshot taken with the “link labels near ends” sample in the documentation below:
Would there be a way to always have some sufficient margin at the left of the label so that it would be all right at all angles? I tried adding some margin to the TextBlock but it did not seem to do anything. I also tried segmentOffset but no success.
