Starting V2.3, FusionCharts supports dynamic data updates at client side. It means that you can change the entire data of a chart at the client side itself, without having to reload the chart or the page. You can use JavaScript or VBScript to dynamically update the client side data.

The chart below illustrates dynamic client side data change. Click on the buttons "Set to Source 1", "Set to Source 2" or "Set the Original Data" to see the effect.
