Summary
If binned resource utilization data is completely 0 within some window of time, then there are also no usages from entities, in which case zooming in will never expose more entities. We should hide the full entity lane in this case as it takes up a lot of vertical space and the text currently implies there might be something there while there isn't.
Fixing this first would be great already. We can furthermore add a counter for "short entities" to bins, such that we can draw something visually in that full entity lane to make users understand where they need to zoom in. Like a vertical line or something with an increasingly visible gradient relative to the other bins and depending on the amount of "short entities" within a bin.
