flow-histc
Reduce transform stream which computes a histogram over a stream of numeric data.
Installation
$ npm install flow-histc
Examples
var eventStream =hStream = ;// Create some data...var data = 1000 ;for var i = 0; i < datalength; i++data i = Math;// Create a readable stream:var readStream = eventStream;// Create the bin edges... (centering the bins)var edges = 22 ;for var j = 0; j < edgeslength; j++edges j = -0025 + j*005;// Create a new histogram stream:var stream =;// Create a pipeline:readStream;
Tests
Unit tests use the Mocha test framework with Chai assertions.
Assuming you have installed Mocha, execute the following command in the top-level application directory to run the tests:
$ mocha
All new feature development should have corresponding unit tests to validate correct functionality.
