How to design a good statistic software
i'm developing an app in java that need to take some information from a file: these info are like:

    name1:
        integer - date
        integer - date
           .
           .
           .
        integer - date
    name2:
        integer - date
        integer - date
           .
           .
           .
        integer - date
      .
      .
      .
    nameN
       integer - date
       integer - date
           .
           .
           .
       integer - date

Users can select the top name: i explain better:
Choosen number of name app must show a chart with the best trend of name:
Example:

    Name1 in the date x has integer y, in date x+1 has integer y+100, in the date x+2 has integer y-400.
    Name2 in the date x has integer y, in date x+1 has integer y+10, in the date x+2 has integer y+200.
    etc.
So user must see the number of name that has best trand than the others. i hope i explain my problem. i don't know what is the best solution. Can you suggest me something? thanks you very much
