Data and chart for ING savings APY since late 2007

When ING's savings interest rates started plummeting, the graph of the rate over the last several months mysteriously disappeared from the website. I contacted customer support but got nothing useful in reply. So I organized a collection of the data I had kept since September 2007. Here is a chart and data series of ING's savings interest rate.

If anyone knows how to get Google Spreadsheets to graph date-series data in a useful way, please let me know.


Thanks, Exactly the data I was looking for.
