Without interpolation, the following looks quite good as it does not introduce those small errors:

```auto
from(bucket: "default")
  |> range(start: 2024-04-01T00:00:00Z, stop: 2024-04-03T23:59:59Z)
  |> filter(fn: (r) => r["_measurement"] == "Measurement")
  |> aggregateWindow(every: 1d, fn: max)

```

will output

```auto
2024-04-01T00:00:00Z: 10
2024-04-02T00:00:00Z: 39

```
