I wrote this module a very long time ago; you should use something else.

linear-autoscale

example

example.js:

var autoscale = require('./index');

var t = autoscale();

var dataset = [-50, 12, 40, 26];

console.log('d: %j', dataset);
console.log('f(d): %j', t(dataset));
console.log('f_inv(f(d)): %j (expect some numerical decay here)',
  t(dataset).inv(t(dataset))
);

output:

$ node example.js 
d: [-50,12,40,26]
f(d): [0,0.6888888888888889,1,0.8444444444444446]
