Only display value for latest month on visual

[Dragonfury]

I have some sales and dates/Months.

I have a bar chart showing Sales (Y axis) by Month (x axis)

I have a measure that works out projected sales for the current month.

Projected Sales Measure = 

VAR mxp = MAX(Dates[Month])
RETURN
CALCULATE(DIVIDE([Sales Amount],workingDays*workingDaysToDate, Dates[Month]= mxp)

The problem is when I add this measure to the column y-axis/Line y-axis, it auto applies the calculation to all months. I only want to see this column for the current month as below:

Instead, I get something like this:

Any ideas on how I can filter the projected sales to only appear on the current Month x-axis?

@Dragonfury , Update your measure to return  value for only one month

Projected Sales Measure =
VAR CurrentMonth = MAX(Dates[Month])
RETURN
IF(
MAX(Dates[Month]) = CurrentMonth,
CALCULATE([Sales Amount], Dates[Month] = CurrentMonth),
BLANK()
)
