A small module that bins past timestamps into desired intervals and creates a histogram array.
npm install timestamp-binning
js
var timestampBinner = require('timestamp-binning');
//create a new timestamp binner:
var evalPeriod = "week";
var binSize = "day";
var binner = new timestampBinner(evalPeriod, binSize);
//some dummy timestamps (dates) as examples:
var d1 = new Date(2014, 5, 27, 21, 20, 0, 0);
var d2 = new Date(2014, 5, 29, 2, 20, 0, 0);
var d3 = new Date(2014, 5, 28, 23, 20, 0, 0);
//add an array of time stamps:
binner.addTimestamps([d1, d3, d3, d3, d2]);
console.log(binner.hist);
//will output: [ 0, 0, 0, 0, 1, 3, 1 ]
//add a single timestamp
binner.addTimestamp(d1);
console.log(binner.hist);
//will output: [ 0, 0, 0, 0, 2, 3, 1 ]
