Finding the maximum temperature recorded for a day

Hi VipulToshniwal ,

You can try this measure to achieve maximum temperature of a day:

Max_temperature of current day =

VAR _curr =

    SELECTEDVALUE ( 'Table'[timestamp_IST] )

RETURN

    CALCULATE (

        MAX ( 'Table'[Temperature] ),

        FILTER (

            ALL ( 'Table' ),

            YEAR ( 'Table'[timestamp_IST] ) = YEAR ( _curr )

                && MONTH ( 'Table'[timestamp_IST] ) = MONTH ( _curr )

                && DAY ( 'Table'[timestamp_IST] ) = DAY ( _curr )

        )

    )

You will get the result like this:

Here is the demo, please try it:
