Hour Breakdown

dcrow5378 Good catch. Easily fixed:

Hour Breakdown = 
VAR __currentHour = HOUR(MAX('Hours'[Hour]))
VAR __startHour = HOUR(MIN('Data'[Start]))
VAR __endHour = HOUR(MAX('Data'[End]))
VAR __table = GENERATESERIES(__startHour,__endHour,1)
VAR __table1 = ADDCOLUMNS(__table,"__minutes",
    SWITCH(TRUE(),
        __startHour < __endHour && [Value] <> __endHour && [Value] <> __startHour,60,
        __startHour < __endHour && [Value] = __endHour, MINUTE(MAX('Data'[End])),
        60 - MINUTE(MAX(Data[Start]))
    )
)
VAR __table2 = FILTER(__table1,[__minutes]>0)
RETURN
SUMX(FILTER(__table2,[Value] = __currentHour),[__minutes])

Will update.
