Unless I am reading the api incorrectly I haven't been able to figure out a
way to easily filter 2 columns.
Sample data:
var data = google.visualization.arrayToDataTable([
['College', 'Resident Per Year', 'Resident Per Semester', 'Non-Resident
Per Year', 'Non-Resident Per Semester'],
['Undecided',6090,3045,18868,9434],
['Business and Economics',6972,3486,20114,10057]
]);
What I would like to do is build a dashboard with a couple of drop downs,
first a selection filter for "college" then a filter that contains
'Resident, Non-Resident' that would then filter out column 1,2 for
selection of non-resident and 3,4 for resident.
I have the first drop down in the dashboard working correctly, that was the
easy part using existing examples, but I am struggling to do the 2nd drop
down. Am I missing something? Any suggestions?
