Power BI Create Continuous Line Chart at End of Position

Question

I have a line chart which the dark blue line data point ends halfway through the chart, as no future data is yet available.

Is there a way to continue the line throughout the rest of the months on the date X Axis as a straight line with its current end position?

Current measure reads

Actuals = SELECTEDVALUE('Actual Hours'[Average Actual FTE])​

To continue the line you should fill blanks for future dates like this:

Actuals = 
VAR _LastDate =
    CALCULATE(
        MAX('Table'[month]),
        ALL('Table'),
        NOT(ISBLANK('Table'[value]))
    )
VAR _Value =
    CALCULATE(
        SUM('Table'[value]),
        'Table'[month] = _LastDate
    )
RETURN
SWITCH(
    SUM('Table'[value]),
    BLANK(), _Value,
    SUM('Table'[value])
)

_LastDate defines last date with non-blank value and _Value gets value for this date. Inside RETURN we fill blanks with _Value and do nothing to non-blanks.

On my dummy data it looks like:
