average on matrix

Hi , dfs29 

Thanks for your quick response!

According to your description, you want to "For example in line 1 (cf below) I have no values in column 2 so I want to divide by 1".

You can try to use dax code :

Measure = var _t =ADDCOLUMNS( CROSSJOIN( ALLSELECTED('Table'[time]) ,  ALLSELECTED('Table'[user case])) , "mv avg" , [moving average])
var _cur_time = MAX('Table'[time])  
var _column =  MAX('Table 2'[user case])
var _t2 = FILTER( _t,[time] =_cur_time && [user case] = _column)
var _value= SUMX(_t2,[mv avg])+0
var _count  =CALCULATE( COUNTROWS('Table 2') , 'Table 2'[user case] <> "AVG")
var _count2 =COUNTROWS( FILTER(_t , [time]=_cur_time && [mv avg] <> BLANK()))
var _sum =SUMX( FILTER( _t , [time] = _cur_time) , [mv avg])
return
IF( _column= "AVG" , _sum/_count2  ,_value)

Thank you for your time and sharing, and thank you for your support and understanding of PowerBI!
