uncaught exception: No plot target specified

uncaught exception: No plot target specified


I got this error while working with JQPlot Jquery API.

This is due to specifying wrong ID

ID needs to specified as follows.

<div id="testid" > </div>

Also the following Javascript API files need to be included.

JavaScript  Code:

 function drawgraph( data1,data2){
var usedp=Math.ceil( data1/data2*100 );
var freep=Math.ceil( 100-usedp );
//alert( usedp );
//alert( freep );
var data = [
    ['Free %', freep],['Used  %', usedp]  ];
  var plot1 = jQuery.jqplot ('testid', [data],
    {
      seriesDefaults: {
        // Make this a pie chart.
        renderer: jQuery.jqplot.PieRenderer,
        rendererOptions: {
          // Put data labels on the pie slices.
          // By default, labels show the percentage of the slice.
          showDataLabels: true
        }
      },
      legend: { show:true, location: 'e' }
    }
  );
          }
