Is your data query asking for min/max values?

Also, your time steps are odd, probably because you have a fixed return size and the start and end timestamps are further apart than that many hours. Failing to normalize the endpoints makes for weird and unreliable interpolations.

I believe the powerchart is all built in things. I didn't use my own custom query to export it to csv. So I don't think it's asking for min max

You can check this by hitting the ⚙ button, Pens tab, ✎, Aggregation Mode (at the bottom of the dialog).

I checked, Aggregation Mode in Default is set to min/max. But it will better if can export only 1 row for each data.

Your options, according to [Perspective - Power Chart | Ignition User Manual](https://www.docs.inductiveautomation.com/docs/8.1/appendix/components/perspective-components/perspective-chart-palette/perspective-power-chart#properties), are,

> - **aggregateMode** : Mode to use to group the data. Options are: default (MinMax), **Average** , MinMax, LastValue, **SimpleAverage** , Sum, **Minimum** , **Maximum** , DurationOn, DurationOff, CountOn, CountOff, Count, Range, Variance, StdDev, PctGood, or PctBad. Value is string.

Try one of the modes I've highlighted. Each of those should return a single value.
