1There's [VML](http://msdn.microsoft.com/en-us/library/ee384217%28v=vs.85%29.aspx) for IEs<9, maybe you can use it? – Teemu Oct 24 '13 at 09:49

could you have any example code to convert the chart to **image/png;base64** using VML – Hariprasath Oct 24 '13 at 09:57

Unfortenately I can't. I have used VML to show 3D CAD models in IE, but it was ten years ago. You could browse the documentation, if you'd find something usefull... – Teemu Oct 24 '13 at 10:07

If you are also using a <canvas>-element (as in the post you referenced), you can try using ExplorerCanvas, which brings canvas-functionality to old Internet Explorer version (make sure to use conditional tags for loading).
Another possibility, as Teemu mentioned, is using VML. I haven't found any script to convert canvas to VML, but I did manage to find this: svg2vml. I guess there should also be variants of this that work with canvas.

in ie8 we cannot convert the chart to image and again to byte code using excanvas and vml is a huge process – Hariprasath Oct 30 '13 at 12:04
