How to create image of div contains dc charts?

[Sadi]

I want to create image of div contains bar, line, pie.

I am using following example and want to take image of container class.

http://dc-js.github.io/dc.js/examples/filtering.html

I am using html2canvas to implement it. following is the piece of code :

   $("#btnSave").click(function() { 

        html2canvas($(".container"), {

            useCORS: true,

//                        allowTaint:true,

            onrendered: function(canvas) {

                theCanvas = canvas;

                document.body.appendChild(canvas);

                // Convert and download as image 

                Canvas2Image.saveAsPNG(canvas); 

                

                $("#img-out").append(canvas);

                // Clean up 

                //document.body.removeChild(canvas);

            }

        });

    });

It's not working :(

Any idea how to implement it?

Any help is appreciated. I am really stuck this point.
