Hi I am using the Google Visualization: Annotated Time Line for the
first time and have a question.
data.addColumn('date', 'Date');
data.addColumn('number', 'Ad Spend');
data.addColumn('number', 'Revenue');
data.addColumn('number', 'ROI');
I just want the date column fixed. I have 3 dropdownlists from which I
want the other 3 columns. Each dropdown list has a blank field, Ad
Spend, Revenue and ROI... So if a user chooses blank, blank,
Adspend... only the Adspend column should be added to the chart. I am
setting the value through a sqldatasource.
So basically can you choose your columns dynamically? (on user
input)??
Thanks a lot,
Vishwanath.
