Hi Suriya,

What exactly are you trying to achieve?
If this is a new web application, you can first register the web parts. Then you should be able to Save and Load a Chart template from the existing site which has Nevron Chart configured. You may also have to update the data source connection and the expressions used in the Pivot.

Hi,

 I am using nevron chart for Sharepoint in one of our project. We are developing another sharepoint site where we want do display the chart from our existing site? Is there any way we can do this??

Any help will be highly appreciated.
