Chart for Web Forms - How to Use Callbacks to Update a WebChartControl Dynamically

This example shows how to use callbacks to update a WebChartControl dynamically.

In this example, the ASPxTimer.Tick event occurs once a second (the timer's Interval property value is equal to 1000 milliseconds). In the ASPxTimer.Tick event handler, the example calls the chart's PerformCallback that raises the CustomCallback event. In the CustomCallback event handler, new points are generated and added to the chart.
