An example here: http://jsfiddle.net/shrimpboyho/57wZW/

##How to Install

Include the library in your HTML as follows:

<script src="graphy.js"></script>
<script src="your_code.js"></script>

##Documentation

Create a new Graphy() object and send in a canvas.

var canvas = document.getElementById('myCanvas');
var graphymachine = new Graphy(canvas);

Set up some settings such as the number of pixels per one unit and the origin and whether a grid should be present.

graphymachine.setPixelsPerUnit(20);
graphymachine.setOrigin(200,200);
graphymachine.drawGrid();

Graph the function by calling the graph() method with an equation, a color, and line thickness as your arguments.

graphymachine.graph("x * Math.sin(10 * x)", "orange",2);
