Transpose table with calculation

CornelisV This will calculate the number of minutes in a column. See attached PBIX below sig.

Column = 
    VAR __Phase = [Phase]
    VAR __Current = [Date time]
    VAR __Type = 
        SWITCH( TRUE(),
            __Phase = "End heating", "Start heating",
            __Phase = "End cooling", "Start Cooling"
        )
    VAR __Result = 
        SWITCH(
            __Phase,
            "Start heating", 0,
            "Start cooling", 0,
                VAR __DateTime = [Date time]
                VAR __Result = MAXX( FILTER( ALL( 'Table' ), [Date time] < __DateTime && [Phase] = __Type ), [Date time] )
            RETURN
                __Current - __Result
        )
RETURN
    __Result * 60 * 24
