Thanks Daniel. There is an improvement, though not yet solved. After correcting the syntax and following the guide in the documentation, the pop-up message now: *"The first and second columns must be entity and time."*
This suggests the issue now is with the format of the data in the Google spreadsheet. After creating my columns, the first column is entity (as I am aware of) with string values. The second column is in date with this format *'2009/0/3"* as an example. I opine this will reflect a similitude of *new date (2009,0,3)*. I also click on the* "Format"* on the menu bar of the spreadsheet to pick *"Date"* as the format, hoping this will change the format to the desired. But, the error message is still same. Thanks for the understanding and anticipated assistance. -- You received this message because you are subscribed to the Google Groups "Google Visualization API" group.
