KendoUI chart - how do I show animation while loading data?

Displaying and hiding the loading animation is:

// Display progress
kendo.ui.progress($("#loading"), true);

// Hide progress
kendo.ui.progress($("#loading"), false);

Then you should use requestStart and requestEnd events in the DataSource for knowing when to show or hide the progress animation.

The DataSource of the Chart would be:

dataSource    : {
    transport   : {
        read: {
            url:...
        }
    },
    sort        : {
        field: "year",
        dir  : "asc"
    },
    requestStart: function () {
        kendo.ui.progress($("#loading"), true);
    },
    requestEnd  : function () {
        kendo.ui.progress($("#loading"), false);

    }
},
