QUESTION: how could I not group data by the DATETIME value?

[lanyusea]

I have my data like that: test date frame index test dataset and the values

and it can be successfully updated

but the result looks really strange:

The view query is

SELECT `Dataset` AS `Dataset`,
      `Date` AS __timestamp,
      AVG(`RPE`) AS `AVG(RPE)`
FROM database.my_test
GROUP BY `Dataset`,
      `Date`
ORDER BY `AVG(RPE)` DESC
LIMIT 50000;

and the view results is

I relealize the problem may be caused by GROUP BY Date but it seems to be a default selection I cannot withdraw. (or I don't know how)

What I expect is it samples data with same PatchSet and different FrameIndex then do the box plot.

So I'm wondering if there is any way I can achienve this kind of virtualization?
