GitHub user inctl created a discussion: Time-Series Gap Filling in Superset:
Apply Resampling to the Entire Target Period
### Apply Resampling to the Entire Target Period
Superset version: 4.1.2 and 6.1.0
## Requirement:
I need to be able to view an area or bar chart in which missing data points are
set to 0.
I have set a time granularity and enabled “Resample to zero” for the time axis.
However, the resampling only applies between two data points.
## Case
If I have only one data point per day, I end up with a bar that spans the
entire day.
I want all hourly data points to be set to 0.
Since version 6.1.0, I’ve noticed that by setting a JSON echart with this
value, the result is correct.
But I can’t make the start and end values dynamic.
```
{
"xAxis": {
"min": "2026-07-01 00:00:00",
"max": "2026-07-02 00:00:00"
}
}
```
## Conclusion
It would be helpful if this were handled by default with the resample.
And if possible, to have an auto-resample aligned with the time granularity,
allowing the time granularity filter to be used in a dashboard.
Thank you advance,
