Hi @Anonymous ，

Based on your description, you can do some steps as follows.

1. Create a column to group by hour.

_hour = HOUR([TIME])

2. Create a measure.

calculated_value =

var x1=CALCULATE(MIN('Case2_2'[TIME]),ALLEXCEPT(Case2_2,Case2_2[_hour]))

return

CALCULATE(MIN('Case2_2'[VALUE]),FILTER(ALL('Case2_2'),'Case2_2'[TIME]=x1))

3. Create a table visual.

Result:

Hope that's what you were looking for.

@Anonymous , Create a column like this as suggested in last update

TIME new = [TIME].date + time(hour([TIME],0,0)

And then use this in visual with measure given below

firstnonblankvalue(Table[TIME], max(Table[Value]))

As i am using the direct query , the solution above is showing error.

You should be able to get your result as follows

- in the query editor, split your datetime column at the space and convert to date and time

- add a column by selecting your time column and in the Time pull down choose Hour

- load the table

- make a table visual with the Date column and the new hour column

- also add the Value column and choose min as the aggregation (or write a measure with MIN() )

Note: if you table is already loaded, you could also do the same with DAX columns, but I would do it in query.
