var dataset = [
    { date: '05-05-2014', clicks: 10 },
    { date: '05-05-2014', clicks: 10 },
    { date: '05-05-2014', clicks: 20 },
    { date: '05-05-2014', clicks: 30 },
    { date: '05-05-2014', clicks: 40 }
];


console.log('(chaining pluck) sum', _(dataset).pluck('clicks').sum().value());
console.log('(chaining pluck) mean', _(dataset).pluck('clicks').mean().value());
console.log('(chaining pluck) median', _(dataset).pluck('clicks').median().value());

console.log('(chaining string iterator) sum', _(dataset).sum('clicks').value());
console.log('(chaining string iterator) mean', _(dataset).mean('clicks').value());
console.log('(chaining string iterator) median', _(dataset).median('clicks').value());

console.log('(chaining function iterator) sum', _(dataset).sum(function (value) {
    return value['clicks'];
}).value());
console.log('(chaining function iterator) mean', _(dataset).mean(function (value) {
    return value['clicks'];
}).value());
console.log('(chaining function iterator) median', _(dataset).median(function (value) {
    return value['clicks'];
}).value());
