The DataTable constructor requires a very specific JSON format; if you aren't using that format, the constructor will throw an error and your chart will not draw. I can help you get your chart working if you share your code. I also suggest that you search this group for examples of creating charts from SQL queries (most examples here use PHP and MySQL, though you can easily substitute a different database in most cases).
