Visual Bug with Column Stacked Apex Charts

Hi there,

I’m currently working with some column stacked apex charts and I’ve noticed a strange phenomenon.

Normally the chart in question shows the last 24 hours with a 1h aggregation:

So when a new hour starts, like in this case at 16:02h. As the only series whose devices have sent information are the Rack and the AC, they appear to be drawn in front of the whole chart. The other series are left behind.
As you can see, different ‘layers’ have formed:
Those that haven’t sent are stacked behind, and the two that have sent are not stacked.

As I understand it, the correct approach to this would be to draw the 2 series whose devices have send stacked in the new hour column, but not to change the rest of the chart.

Is this a bug?

Thank you in advance,

Hi there,

Anyone knows if this is a bug?
