How to add a new series dynamically in Chart?

Platform: jQuery |
Control: ejChart |
Published Date: February 11, 2015 |
Last Revised Date: July 1, 2019

Essential Chart supports dynamically customizing all the properties with the instance of Chart. You can create an instance for Chart by calling the ejChart constructor method with the string instance as parameter. To add a new series dynamically, add a series object to the series collection of chart instance. The following code example illustrates the above.

JS

<div id="container"></div>
<input type="button" onclick="AddSeries()" value="Add Series" />
<script type="text/javascript">
function AddSeries() {
    var Chart = $("#container").ejChart("instance");
    //Adding a new series dynamically using Chart instance
    Chart.model.series[Chart.model.series.length] = {
        points: [{ x: 'Australia', y: 20 }, { x:     'China', y: 15 }], 
        name: 'Dynamic Series' 
    }
    //Redrawing chart after updating series collection
    Chart.redraw();
}
$(function () {
    $("#container").ejChart({
        series: [{
            points: [{ x: 'India', y: 25 },
                { x: 'Australia', y: 32 },
                { x: 'China', y: 41 },
                { x: 'Japan', y: 30 },
                {x: 'France', y:28}
            ]
        }]
    });
});
</script>
