I am also trying the above code locally.

here is the code:

<html>
  <head>
    <script type="text/javascript" src="../JQuery/excanvas.js"></script> 
    <script type="text/javascript" src="../JQuery/jquery.js"></script> 
    <script type="text/javascript" src="../JQuery/jquery.jqplot.js"></script> 
    <script type="text/javascript" src="../JQuery/jqplot.categoryAxisRenderer.min.js"></script> 
    <script type="text/javascript" src="../JQuery/jqplot.barRenderer.js"></script> 

    <script type="text/javascript" src="../JQuery/jqplot.categoryAxisRenderer.min.js"></script> 
    <script type="text/javascript" src="../JQuery/jqplot.canvasTextRenderer.min.js"></script> 
    <script type="text/javascript" src="../JQuery/jqplot.canvasAxisLabelRenderer.min.js"></script> 
    <link rel="stylesheet" type="text/css" href="../JQuery/jquery.jqplot.css" />

    <script type="text/javascript"> 
      $(document).ready(function(){  
        var plot1 = $.jqplot ('chart3', [[3,7,9,1,4,6,8,2,5]]);
      }); 
    </script>
  </head>
  <body>
    <div id="chart3" style="width:400px; height:300px;"></div>
  </body>
</html>

But when I run this code, it gives me javascript error for “excanvas.js” file. like “parentnode” is null or not an object. I am using IE8.

    I tried the code and it works fine.
    To be 100% honest I run it in ie9 with compatibility mode of ie8, then ie7 (since I update my browsers regularly, I recommend doing the same and asking clients to do the same as well) and it works fine.

    The only issue I might expect you can have here is that these scripts:

        <script type="text/javascript" src="../JQuery/jqplot.categoryAxisRenderer.min.js"></script> 
    <script type="text/javascript" src="../JQuery/jqplot.barRenderer.js"></script> 
    <script type="text/javascript" src="../JQuery/jqplot.categoryAxisRenderer.min.js"></script> 
    <script type="text/javascript" src="../JQuery/jqplot.canvasTextRenderer.min.js"></script> 
    <script type="text/javascript" src="../JQuery/jqplot.canvasAxisLabelRenderer.min.js"></script>

    … are located in plugins folder which you should have if you downloaded the jqPlot from their site.

    To test quickly if this is the issue you can simple delete the aforementioned scripts and the code should work just fine as it is not using them at all.
