I have generated four charts on the html page using amchart in 4 divs respectively. On each div there is a link for export the chart. The charts are generated using multiple SVG. I want to save the chart separately as an image on client side by clicking the export link.
Finally, I got my solution. I convert all the svg to image one by one and write it in a div using http://www.battlehorse.net/page/topics/charts/save_google_charts_as_image.html
And finally I convert the div content to image using http://html2canvas.hertzen.com/index.html. If any one want to convert the text and svg then you need to clone the div content to the new div and then write the converted image to new div and finally convert it to image.
