code revision

I've changed the example from the blog about chart integration from the filtering event.
I want the sum of the salary per office.
I wonder whether my code is clumsy or is it good.
Can you suggest if it's ok or there is a more datatables idiomatic way to do that?
Anyway I think it is working.

function zip(data) {
    a1 = data[0];
    a2 = data[1];
    a3 = [];
    for(var i = 0; i < a1.length; i++) {
        a3.push([a1[i], a2[i]]);
    }
    //console.log('a3',a3);
    return a3;
}
 
function chartData(table) {
    var counts = {};
    // Count the sum of the salary for each office
    $.each(zip(table
        .columns( [2,5], { search: 'applied' })
        .data()),
        function (index, val) {
            // console.log(val);
            if (counts[val[0]]) {
                counts[val[0]] += Number(val[1].replace(/[^0-9.-]+/g,""));
            } else {
                counts[val[0]] = Number(val[1].replace(/[^0-9.-]+/g,""));
            }
        });
 
    // And map it to the format highcharts uses
    return $.map(counts, function (val, key) {
        return {
            name: key,
            y: val,
        };
    });
}

Thank you for your support

Looks fine, and if it's working, that's the main thing
