Microsoft JScript runtime error: Unable to set value of the property 'BarRenderer': object is null or undefined
i want to display a Chart with Point Labels inside my asp.net mvc as mentioned in this link http://www.jqplot.com/tests/point-labels.php , but when i navigate to the intended view i got the following error:-

    Microsoft JScript runtime error: Unable to set value of the property 'BarRenderer': object is null or undefined inside the `d.jqplot.BarRenderer.prototype=new d.jqplot.LineRenderer()` inside the `jqplot.barRenderer.min.js`
my view looks the following:-

    @{
        ViewBag.Title = "About Us";
    }
    @section scripts{
    <script src="../../Scripts/jqplot/jqplot.barRenderer.min.js" type="text/javascript"></script>
    <script src="../../Scripts/jqplot/jqplot.categoryAxisRenderer.min.js" type="text/javascript"></script>
    <script src="../../Scripts/jqplot/jqplot.pointLabels.min.js" type="text/javascript"></script>
    
        }
       <script type="text/javascript">
        $(document).ready(function () {
    
    var line1 = [14, 32, 41, 44, 40, 47, 53, 67];
      var plot1 = $.jqplot('chart1', [line1], {
          title: 'Chart with Point Labels',
          seriesDefaults: {
            showMarker:false,
            pointLabels: { show:true }
          }
      });
    });
        });
    </script>
    
    <div id = "chart1">
    </div>

so what might be the problem ?
