kendo ui chart loading progress

Kendo UI chart - how do I show animation while loading kendo chart data?

HTML code-sample

<div id="example">

   <div class="demo-section k-content wide sel-chart-wrapper">

       <div id="chart"></div>

   </div>

</div>

JQuery code-sample

 $(function () {

        //Used to display progress.

        kendo.ui.progress($("#chart"), true);

        //Used to hide displayed progress.

        kendo.ui.progress($("#chart"), false);

    });

For Kendo DataSource

  dataSource: {

        requestStart: function () {

            kendo.ui.progress($("#chart"), true);

        },

        requestEnd  : function () {

            kendo.ui.progress($("#chart"), false);

        }

    }
