This is an Excel spreadsheet that pulls Domino XML data over HTTP and charts the result. ( Excel 2003 is required for this demo)

If you are on a network, you can change or delete the [Jump Number, Data, Altitude, Free Fall Time] table and then refresh the XML to reverse your changes. The XML data is from a live Domino server.
http://www.msdomino.net/orders.nsf/ordersxml?openagent is the URL that provides the data. The public view is found at http://www.msdomino.net/orders.nsf/customer%20orders?OpenView

Update: I've added buttons to delete and refresh the data.
