Note: Showing all labels can more easily cause overlapping labels if they are too long., like that is the case in out UI tests. Might be possible to fix this by making the labels multiline maybe:

Could it maybe be a simple solution to just offset every 2nd label in the same way that we currently have every 2nd label hidden?
I.e. offset the label by one line height for every 2nd one.

@Starker3 might be a solution. But guess this looks ugly, when there actually would be enough space to display it on the same line.
