    amplitude-viewer

    render amplitudes like an oscilloscope in the browser given arrays of data

    example

    var ascope = require('amplitude-viewer')(fn);
    ascope.appendTo('#scope');
     
    setInterval(function () {
        ascope.setTime(Date.now() / 1000);
        ascope.draw(fn);
    }, 50);
     
    function fn (t) {
        return sin(440) * 0.25 + sin(441) * 0.25 + sin(880) * 0.5;
        function sin (x) { return Math.sin(2 * Math.PI * t * x) }
    }

    methods

    var viewer = require('amplitude-viewer')

    var ascope = viewer()

    Create a new viewer.

    ascope.appendTo(target)

    Append the ascope element to target, a query selector string or container element.

    ascope.setTime(t)

    Set the drawing time in seconds.

    ascope.setOffset(t)

    Set an offset to the drawing time in seconds.

    ascope.setDuration(d)

    Set the width of the time window.

    ascope.draw(fn)

    Draw a wave according to fn(t), which should return an amplitude from -1 to 1 give a time t in seconds.
