wrong dates in line chart

It's hard to guess. Buyt you could try something like this.

AP_TRIAL_BALANCE_OPENNING_BALANCE =
VAR Openning_Debit =

CALCULATE (
[AP_TRIAL_BALANCE_DEBIT],
FILTER (
ALL ( '*Dates' ),
'*Dates'[Date] < MIN ( '*Dates'[Date] )
)
)

VAR Openning_Credit =

CALCULATE (
[AP_TRIAL_BALANCE_CREDIT],
FILTER (
ALL ( '*Dates' ),
'*Dates'[Date] < MIN ( '*Dates'[Date] )
)
)

VAR Openning_Balance = Openning_Debit - Openning_Credit

RETURN

CALCULATE(
IF (
ISBLANK ( Openning_Balance ) && MAX(fact table[date]) <= MAX('*Dates'[Date]),
0,
FORMAT(Openning_Balance, -0.000)
)
)

Thank you  very much it worked 
CALCULATE(
IF (
ISBLANK ( Openning_Balance ) && MAX(fact table[date]) <= MAX('*Dates'[Date]),
0,
FORMAT(Openning_Balance, -0.000)
)
)
