Previously, due to the way
Direction#isHorizontal()
andDirection#isVertically()
are implemented (simply ignoringUNDEFINED
), an undefined layout direction resulted in a horizontal stacking of labels: left-to-right.As I feel vertically stacking is the more natural choice, I changed the behavior for undefined.
Note that for layered the direction is always right (internally during node label placement). For other layouters it can happen though that the direction is undefined as they do not support the option at all.
That being said, I tend to suggest to use a different layout option to decide on the stacking dimension than the layout direction.
