Creating a dynamic Long-Term Value Line Chart

I did mostly figure this out. Here is my intended end result (the only issue is I must have 5 years present in the legend in order for the measure to work properly):

Here is my column/measure set up

LTVYearSortOrder = 
DATATABLE(
    "LTV Year", STRING,
    "Sort Order", INTEGER,
    {
        {"Year 1", 1},
        {"Year 2", 2},
        {"Year 3", 3},
        {"Year 4", 4},
        {"Year 5", 5}
    }
)

LTV Years = CALCULATE(VALUES(LTVYearSortOrder[LTV Year]), ALL(LTVYearSortOrder))

LTV Calculation = 
VAR Max_Year = CALCULATE(MAX('Calendar'[Year]), ALLSELECTED('Calendar'))
VAR Year_1 = 
    CALCULATE(
        [Revenue],
        'Acquisition Calendar'[Year] = MIN('Calendar'[Year])
    )
VAR Year_2 = 
    CALCULATE(
        [Revenue],
        'Acquisition Calendar'[Year] = MIN('Calendar'[Year]),
        'Calendar'[Year] = MIN('Calendar'[Year]) + 1
    )
VAR Year_3 = 
    CALCULATE(
        [Revenue],
        'Acquisition Calendar'[Year] = MIN('Calendar'[Year]),
        'Calendar'[Year] = MIN('Calendar'[Year]) + 2
    )
VAR Year_4 = 
    CALCULATE(
        [Revenue],
        'Acquisition Calendar'[Year] = MIN('Calendar'[Year]),
        'Calendar'[Year] = MIN('Calendar'[Year]) + 3
    )
VAR Year_5 = 
    CALCULATE(
        [Revenue],
        'Acquisition Calendar'[Year] = MIN('Calendar'[Year]),
        'Calendar'[Year] = MIN('Calendar'[Year]) + 4
    )
RETURN
VAR Numerator = SWITCH(
                    SELECTEDVALUE(LTVYearSortOrder[LTV Year]),
                    "Year 1", Year_1 + (0 * Year_2) + (0 * Year_3) + (0 * Year_4) + (0 * Year_5),
                    "Year 2", IF(MIN('Calendar'[Year]) + 1 > Max_Year, BLANK(), Year_1 + Year_2 + (0 * Year_3) + (0 * Year_4) + (0 * Year_5)),
                    "Year 3", IF(MIN('Calendar'[Year]) + 2 > Max_Year, BLANK(), Year_1 + Year_2 + Year_3 + (0 * Year_4) + (0 * Year_5)),
                    "Year 4", IF(MIN('Calendar'[Year]) + 3 > Max_Year, BLANK(), Year_1 + Year_2 + Year_3 + Year_4 + (0 * Year_5)),
                    "Year 5", IF(MIN('Calendar'[Year]) + 4 > Max_Year, BLANK(), Year_1 + Year_2 + Year_3 + Year_4 + Year_5)
                )
VAR Denominator = 
    CALCULATE(
        [Active Donors],
        'Acquisition Calendar'[Year] = MIN('Calendar'[Year])
    )
VAR LTV = DIVIDE(Numerator,Denominator,BLANK())
RETURN
IF(Numerator = 0, BLANK(), LTV)

LTV = 
IF(
    ISBLANK([LTV Calculation]),
    Blank(),
    [LTV Calculation]
)

Good luck and Godspeed to you all if you ever have the misfortune of having to create one of these yourself.
