You should use NumberFormat (
http://code.google.com/apis/chart/interactive/docs/reference.html#numberformatter),
with the pattern field (still undocumented).
var formatter = new google.visualization.NumberFormat({pattern: '0.00%'})
formatter.format(data, your_data_column_number_zero_based);
See example:
