[Bug]: Aggregation over time hides partial or empty data #1136
Description
Bug description
When a timeseries has gaps with empty data, when zooming out to the point that the gap would be aggregated into a single rendered data point, the empty or partial indicators are no longer shown. This removes a critical signal while troubleshooting issues.
Expected behavior
Aggregation over time must keep showing empty / partial.
Steps to reproduce
- Find a timeseries with a gap.
- Zoom out far enough that the gap is covered by a "pixel".
- See the indicators for partial / empty data go missing.

@ktsaou is this an aggregation issue at the Agent, in Cloud, or both?

@ralphm based on the issue description, I would say that the cloud is working as expected:
point annotationsbetween different series, we always keep any non null value, meaning that if a series that the cloud aggregates contains a non null value aspartial dataoroverflow, we would set it.ralphm commentedon Apr 14, 2026
@stelfrag Can you have a look at this?
