Help - Trend chart

Hello manojk_pbi 

One of the solutions would be to create one Calculated column in the table with below logic,

flag = 
VAR CurrentYear = YEAR(TODAY())
VAR RowYear = YEAR([MMMYY])
VAR RowMonth = MONTH([MMMYY])
RETURN
IF(
    RowYear = CurrentYear,                  
    TRUE(),
    IF(
        RowYear < CurrentYear,              
        RowMonth = 12,                      
        FALSE()                                 )
)

and use this flag column as a visual level filter as in below picture.

Hope this helps:) 

Thanks for your reply. It is helpful. I am changing the graph to column chart in which we can avoid other months
