Details

Generally, the functor gets the value of the first item but it's not mandatory.

Note, the same effect of grouping will be achieved if you omit the functor at all.


Let's assume that you have the following data set initially:

initial_data = [
    {id:1, sales:262, year:2003, company:"Company 3"},
    {id:2, sales:527, year:1998, company:"Company 1"},
    {id:3, sales:629, year:2006, company:"Company 3"},
    {id:4, sales:403, year:2008, company:"Company 2"},
    {id:5, sales:377, year:2006, company:"Company 2"}
];

You group the data like this:

$$("mychart").group({
    by:"company",
    map:{
        sales:["sales", "sum"],
        year:["year", "any"]
    }
});

And get a new data set:

new_data = [
    {id: "Company 1", sales: 527,  year: 1998}
    {id: "Company 2", sales: 780,  year: 2008}
    {id: "Company 3", sales: 891,  year: 2003}
];
