How can you refresh a Pivot Chart ?

I have a small Pivot Table which has an associated Pivot Chart. I have just added some data to the Pivot Table and refresh it. How can I get the Pivot Chart to update automatically to include the new data I've added ? Kevin.

Thanks. The code does update the Pivot Table, but I have a Pivot Chart (Pie Chart) which I also want to update automatically when the Pivot Table has additional data added. How can you update the Pie Chart without having to create a new one. Thanks Kevin.
