Line chart data label on min, max, current points only for dynamic hierarchy (sample solution)

v-prasare  Thank You

i have been playing around with chatgpt to help me , the below works on gettinfg the last month total only but not when i roll up to qtr where i want the ucrrent or last qter total to display

This works for last only that has start of month date
LastDateValueLabel =  
  VAR MaxFactDate =
    CALCULATE(
        MAX(FACT[Date]),
        ALLSELECTED('Calc_Calendar')
    )
RETURN
IF(
    MAX('Calc_Calendar'[Date]) = MaxFactDate,
       FACT[ActualBaseMeasAgg],
    BLANK()
)

Now trying date hierarchy:

VAR CurrentMaxDate =
    CALCULATE(
        MAX(FACT[Date]),
        ALLSELECTED('Calc_Calendar')
    )

VAR CurrentPeriod =
    SWITCH(
        TRUE(),
        ISINSCOPE('Calc_Calendar'[DateStartOfMonthDescr]), "Month",
        ISINSCOPE('Calc_Calendar'[DateFinQuarterDescr]), "Quarter",
        ISINSCOPE('Calc_Calendar'[DateFinYearDescr]), "Year",
        "Other"
    )

RETURN
SWITCH(
    CurrentPeriod,
    "Month",
        CALCULATE(
            FACT[ActualBaseMeasAgg],
            FILTER(
                ALL('Calc_Calendar'),
                'Calc_Calendar'[Date] = CurrentMaxDate
            )
        ),
    "Quarter",
        CALCULATE(
            FACT[ActualBaseMeasAgg],
            DATESQTD('Calc_Calendar'[Date])
        ),
    "Year",
        CALCULATE(
            FACT[ActualBaseMeasAgg],
            DATESYTD('Calc_Calendar'[Date])
        ),
    BLANK()
)
