Hi Sunil,
I haven’t gotten things to work in IE8 either. I tested things in jsfiddle (http://jsfiddle.net/QwZuf/104/) and it worked there, but not in my IE8 browser. The errors I get in IE are…
Message: ‘m[…].y’ is null or not an object
Line: 181
Char: 361
Code: 0
URI: http://localhost/canvasjs.min.js
Message: ‘dataPoints[…]’ is null or not an object
Line: 75

Message: ‘this.legend.items’ is null or not an object
Line: 85
Char: 313

I’ve tested things in Chrome and Firefox where I’m able to line plot, bar graph and create pies.
