Jquery chart stopped showing all of a sudden

Question

I have the following code, which was creating a graph on the confirmation page of my Drupal Webform (I created a stress test), and has been working fine for several weeks. Now all of a sudden this entirely just stopped working.

Anyone have any ideas why it stopped working, and how to get it working again? I didn't make any changes to the code. I have been tearing my hair out.

jQuery(function($) {
    var ticks = [], vals = [];
    var one = $('#edit-submitted-physical-state, #edit-submitted-mental-state, #edit-submitted-feelings-of-belonging, #edit-submitted-feelings-of-justice, #edit-submitted-feelings-of-integrity, #edit-submitted-weight-management, #edit-submitted-emotional-ease, #edit-submitted-feelings-of-stimulation, #edit-submitted-feelings-of-justice, #edit-submitted-feelings-of-relationship, #edit-submitted-feelings-of-satisfaction')
        .each(function(i, el) {
            vals.push(Number(el.value));
            ticks.push($('label[for="'+el.id+'"]').text().replace('Feelings of ', '').replace(': ', '').replace(' State', '').replace(' Ease', '').replace(' Management', '').replace(' Control', ''));
        });

    var plot1 = $.jqplot('chart1', [vals], {
        seriesDefaults: {
            renderer: $.jqplot.BarRenderer
        },
        axes: {
            xaxis: {
                renderer: $.jqplot.CategoryAxisRenderer,
                ticks: ticks
            },
            yaxis: {
            min: 0,
        max: 20, 
        }


        }
    });
});

In my head section I have the following

<script language="javascript" type="text/javascript" src="http://www.beatinganger.com/scripts/jquery.jqplot.js"></script> 
<script language="javascript" type="text/javascript" src="http://www.beatinganger.com/scripts/jqplot.barRenderer.js"></script> 
<script language="javascript" type="text/javascript" src="http://www.beatinganger.com/scripts/jqplot.categoryAxisRenderer.js"></script> 

<link rel="stylesheet" type="text/css" href="http://www.beatinganger.com/scripts/jquery.jqplot.css" />

Answer 1

jqPlot is expecting an ID, but you're using a class on your page. Try changing it to id="chart1"

Answer 2

Got it. May be that server is down or file have been moved. So, save .js file from that server and then use it from local directory.
