Two time Frames on Same Graph

I created a Calendar Table.  But I still do not know how to get the YTD amount in there.  I am struggling quite a bit to get this to work.  

I tried to use chatGPT now that I have this table but its still not working. 

AverageVisitsPerDoctorForSelectedMonthOrYTD = 
VAR SelectedMonthEnd = EOMONTH(MAX('Calendar'[Date]), 0)
VAR YearStart = STARTOFYEAR('Calendar'[Date])
VAR ProviderFilter = ALLSELECTED('SEP YTD'[Provider])
VAR TotalPatients =
    CALCULATE(
        DISTINCTCOUNT('SEP YTD'[Patient Name]),
        ProviderFilter,
        'SEP YTD'[Service Date] >= YearStart && 'SEP YTD'[Service Date] <= SelectedMonthEnd
    )
VAR TotalServiceDays =
    CALCULATE(
        DISTINCTCOUNT('SEP YTD'[Service Date]),
        ProviderFilter,
        'SEP YTD'[Service Date] >= YearStart && 'SEP YTD'[Service Date] <= SelectedMonthEnd
    )
RETURN
IF(
    TotalServiceDays > 0,
    DIVIDE(TotalPatients, TotalServiceDays),
    BLANK()
)

For example when I select January in the filter I should expect the Month output and the YTD output be the same. 

Sorry I am just so new at this that I am struggling pretty badly.

This is my date table.
