Last N weeks on column chart as x axis

[uayan]

I want to create dynamic column chart represents count of project number by week number. 

For example:

I have date column as a date format and date table shows week number.

Actually I want to create this chart as last 52 weeks not last 6 months.

@uayan , if there is no slicer you can get last 52 week using

last 52 weeks =
var _min1 = today() -WEEKDAY(today() ,2) +1 //Monday week start
var _max = _min1 +6

var _min = _min1 -(51*7)
return

CALCULATE([Net], FILTER('Date','Date'[Date] >=_min && 'Date'[Date] <= _max))

if you want to select a date/week and then want 52 week, then your slicer need to me on an independent date table

//Date1 is independent Date table, Date is joined with Table
new measure =
var _today= maxx(allselected(Date1),Date1[Date])
var _min1 = _today -WEEKDAY(_today ,2) +1 //Monday week start
var _max = _min1 +6

var _min = _min1 -(51*7)
return

CALCULATE([Net], FILTER('Date','Date'[Date] >=_min && 'Date'[Date] <= _max))

What is the meaning of [Net] ?
