Pixel Approximate Entropy

This repository shares implementations of Pixel Approximate Entropy, a visual complexity measure for estimating how easy line charts are to read. A detailed description of our research is presented in our recent IEEE InfoVIS 2018 paper At a Glance: Pixel Approximate Entropy as a Measure of Line Chart Complexity.

Usage

The javascript package can be installed with npm:

npm i pae

Optionally use the --save option to add to package.json dependencies.

The package can then be included in your index.html with:

<script src="node_modules/pae/lib/pae.js"></script>

Alternately, you can just include pae from jsdelivr cdn:

<script src="https://cdn.jsdelivr.net/npm/pae/lib/pae.js"></script>

Once you have included pae in your webpage, it can be used as follows:

var pae_meas = new pae.PAE(300, 200);
console.log(pae_meas.pae(data)); // data is javascript array of numbers
