I want to access to chart data on client-side by using javascript. I write code like this. <script language="JavaScript" for="Chart1" event="MouseDown(sender, args)"> <!-- var point = args.Point; var series = args.Series; var nValue = Chart1.Data.X[0,0] alert(nValue); --> </script> It doesn't work. javascript error. Plz let me know the way to access chart data. Chart is rendered as .Net thank you.
