Detected Changes Values in Google Spreadsheet

[Peppi]

Hi,

I am using the Visualization API to retrieve data from a Google Spreadsheet and then displaying it in my Google Gadget. I have the data set to refresh, which works fine. What I would like to do though is to compare numeric values to what they were before. If they have gone up, I want to display the number in green. If it has gone down, then I would like to show it in red. Is there a way to get the before values? Or do I need to store the old values in an array and compare them with the new values on every refresh?

Thx.

I don't think that gadgets support this.
