<!-- This sample shows the event parameters, and their values, when centerLabelChanged event is triggered-->
<div id="indicatorDiv">Event name: <strong> centerLabelChanged </strong> 
    
    <p>Triggered every time the text within the center label of the doughnut chart changes.</p>
    <p>All events, when triggered, will provide two parameters for the handler - <strong> eventObj </strong> (object containing information generic to all events) and <strong> dataObj </strong> (object containing information specific to an event).</p>
    <p>Roll the mouse pointer over the slices of the doughnut chart to change the center label text and trigger the event. Scroll down to the table rendered below the chart to view information contained in the dataObj object. To view information contained in the eventObj object, open the console.</p>
