生成2013年所有的日期，并随即生成一个对应的值

gen-array.js

'use strict';

var start = new Date(2013, 0, 1);
var end = new Date(2014, 0, 1);

var data = [];

while (start < end) {
    data.push( [start.getTime() / 1000, Math.floor( Math.random() * 6) ] );
    start = new Date(start.setDate(
            start.getDate() + 1
        ));
}

gen-object.js

'use strict';

var start = new Date(2013, 0, 1);
var end = new Date(2014, 0, 1);

var dates = {};

while (start < end) {
    var prop = start.getTime() / 1000;
    dates[prop] = Math.floor( Math.random() * 6 );
    start = new Date(start.setDate(
            start.getDate() + 1
        ));
}
