API

As soon as the next version is ready (very soon hopefully), http://graph.tk/ will by replaced with the beta version currently available at http://aantthony.github.com/graph.tk/. The "Powerful Method" API described below is for new version. Sorry for any inconveniences.

Poweful Method

Use the following code to generate a graph.

<iframe src="http://graph.tk/" id="my_graph" style="width:500px;height:400px"> </iframe>
<script>
var my_graph=document.getElementById("my_graph"); my_graph.onload=function(){ function g(m){ my_graph.contentWindow.postMessage(m,"http://graph.tk"); }; g("add:x^3+1"); g("add:e^x"); // g("block"); - Block movement by user g("center:0,0"); } //Methods include: add, block, empty, scale, translate, center </script>

Old Method

Specify the equations via use of the url hash. An example: http://graph.tk/#y=x^2

<iframe src="http://graph.tk/#y=sin(x)"></iframe>
