Combination Line Charts with 2 measure for different ID selected by user

[Tina_345]

Hi Cognos Gurus,
    I am running into one issue where I am trying to use a combination line chart with 2 measures for different ID's selected by user.
    I was able to use one of those combination charts (bar + Line) and updated Bar section to line.
    However I can run it for only one ID (selected by interactive report by user).

    Y-Axis:
       Measure 1: Percent_Value_1
       Measure 2: Percent_Value_2
   
    X Axis: Months as a number

    ID : 100, 200 , 300 , 400 (selection by user)


   If you run for one ID, it is ok.However I don't see any option to group by ID in case of multiple selection.
   Unlike in simple Line chart where you have x and y axis  and can be group by different ID's.


  Thanks and Regards
