    Excel array formula, offset, index, match...

    Hi, I'm trying to separate several datasets from a long table so I can graph the results.

    Sample spreadsheet attached

    Data is in a table containing a name, date and value

    A; B; C;
    Cris; 01-Oct-10; 52
    Dave; 03-Oct-10; 151
    Ella; 03-Oct-10; 65
    Fred; 08-Oct-10; 98
    Bill; 08-Oct-10; 117
    Cris; 08-Oct-10; 62
    Cris; 15-Oct-10; 54
    Adam; 15-Oct-10; 121


    I have used array formulas to separate out the unique dates and names for the axes of
    the table that will be used for the graph: eg


    .......... Adam; ...Bill; ...Cris; ...Dave; ...Ella; ...Fred
    01-Oct-10 .................. 52
    03-Oct-10 .............................151 ....65
    08-Oct-10 etc etc.... 117 62 98
    15-Oct-10 121


    The bit I'm struggling with is the array formula to populate the table. It needs to reference the date in the left col and the name above and fill in the corresponding cells.

    I expect to use index, match, offset - but I just cant get it to work :-/
