RequestData: function (sender, args: Object);
sender. Event source.
args. Event information.
The RequestData event is fired when it is necessary to load data to data source.
To execute the example, the HTML page must contain the BubbleChart component named bubbleChart (see Example of Creating the BubbleChart Component). Handle the RequestData event:
bubbleChart.RequestData.add(function (sernder, args) { console.log("Missing data is requested"); });
After executing the example, each time the RequestData event occurs, the browser console shows a message informing that missing data is requested.
