Displaying different data point in line charts

[Anonymous]

Hello Friends,
I have a line chart which has four data points (ABCD). I'm using week as my axis. Now I'm at week 85. So, for week 86, I want only my data point C to be displayed along with the previous ABCD points.

Sorry for my painting skill 😛

@Anonymous ,Not very clear

if you have not selected a week in slicer, you can control the week in your measure 

your need columns like

year Week = if('Date'[Week Number]<10,'Date'[Year]*10 & 'Date'[Week Number],'Date'[Year]&'Date'[Week Number])
OR
Week Rank = RANKX(all('Date'),'Date'[Year Week],,ASC,Dense) //YYYYWW format

measure

Last 2 weeks =

var _max = Maxx(allselected('Date'), [Week Rank])

var _min =_max -2

CALCULATE(sum('Table'[Qty]), FILTER(ALL('Date'),'Date'[Week Rank]>=_min && 'Date'[Week Rank]<=_max ))

There is no issues with the week. I want to display only one data point for the upcoming weeks (i.e) C. I don't want to display the data points ABD.
